I t was a Cain and Abel story rather than the birth of the baby Jesus that got everyone talking over the holidays. The surprise television hit wasn’t Poirot, or Watership Down, or Les Mis, but a music documentary about Bros, the mostly forgotten Eighties pop band, screened quietly on BBC4 late one night. Why did it strike such a chord? For a start, it’s hilarious, but the pathos of the film, particularly at Christmastime, was almost Shakespearean. When I sat down to watch it, to see what all the fuss was about, I didn’t expect to both laugh and cry.

The film sits in the same lane as Anvil, This is Spinal Tap and Popstar: Never Stop Never Stopping. Bros are ripe for the celebrity has-been genre. The brothers were world famous in their heyday, swiftly rocketing to the heights of stardom and wealth, before the screaming stopped and it came to an end. But, even as their stars have faded, they have retained the popstar pretensions and highfalutin’ opinions that are encouraged at the most hysterical levels of fame. Cue the most wonderful lines and meme-friendly quotes.

“I think the letters H-O-M-E are so important because they personify the word home, which means it’s the place that you come and feel safe,” says Matt Goss, with adamantine conviction and a total absence of self-consciousness.

His philosophies and theories keep on coming. “If you see a man sweeping the road that man’s a king to me, he’s one of my kings, [beat], because I’m thankful I don’t have to sweep the road.” CNN is the “thinking man’s reality show”. “I made a conscious decision because of Stevie Wonder to not be superstitious,” he tells us, deadpan. His delivery is absolutely perfect.

Perhaps the best moment is this. “You can’t even f***ing play conkers in England,” Matt muses at one point. “Can we start a petition on Bros please about how ridiculous it is that you can’t play conkers and if you do you got to wear goggles? You can’t play conkers in England, that is the biggest problem.” Luke pauses and replies, sanguine. “I can live with it.” It. Is. Glorious.

Shoplifters Japanese filmmaker Hirokazu Kore-eda’s Shoplifters could be the year’s most disarming film. On first glance, the clan at its centre are just like any other, but their impulsive decision to take in a missing girl begins a series of rug-pulls you wouldn’t expect from a film such as this. A complex heartbreaker, albeit one that starts out looking like the more modest family dramas Kore-eda is known for. GAGA Pictures / Thunderbird Releasing The 15 best films of 2018 14. Game Night “We knew there was a bad version of this movie that could exist,” said Game Night’s co-director John Francis Daley (the kid from Freaks and Geeks). This certainly isn’t it. Starring Jason Bateman and Rachel McAdams as a competitive married couple who mistake an actual kidnapping for a particularly immersive role play game, Game Night is snappy, witty and fully committed to its brilliant, tonally unsettling conceit. Rex The 15 best films of 2018 13. Isle of Dogs Any Wes Anderson film is likely to be offbeat, fastidiously stylish and shot through with the auteur's understated drollery. Isle of Dogs is no different. A stop-motion story of abandoned canines taking on a corrupt human government, it's set in a futuristic Japan and deals with some pretty heavy themes (fascism, ethnic cleansing). Funny and full of heart. The 15 best films of 2018 12. They Shall Not Grow Old Peter Jackson’s First World War documentary is a remarkable step-forward for historical filmmaking. The Lord of the Rings director breathes new life into black and white archive footage from the Imperial War Museum, digitally restoring and smoothing the grainy source material before adding colour and sound. The result is a stunning cinematic experience that vividly brings the past into the present. By using the voices of veteran British soldiers interviewed about their experiences in the trenches, Jackson also includes a fascinating narrative that’s both gripping and informative. A wonderfully apt way to mark the centenary of the Great War. BBC/IWM The 15 best films of 2018 11. First Reformed Nobody knew if Paul Schrader still had it in him to make a film as angry or as barbed as First Reformed. There is the same raw power here as found in his earlier features about tormented loners. Cinephiles will delight in the (sometimes a little self-conscious) references to Ingmar Bergman and Andrei Tarkovsky, but you can’t help but relish the intensity and intelligence in Ethan Hawke’s performance as the tormented, guilt-ridden priest. Picturehouse Entertainment The 15 best films of 2018 10. Black Panther There were two Marvel films released this year, one of which – Avengers Infinity War – was an over-crowded, if ambitious, sequel. The other was a landmark film – not just for Marvel, but for cinema. Black Panther was fit to bursting with selling points, all combining to deliver the studio’s best film: Michael B Jordan’s standout villain, scene-stealing performances from Danai Guria and Letitia Wright, plus the direction of Creed’s Ryan Coogler who proved an inspired appointment. Wakanda forever, indeed. Walt Disney Studios Motion Pictures The 15 best films of 2018 9. Cold War Pawel Pawlikowski’s Cold War, shot in the sleekest black and white, is an effortlessly stylish and romantic drama set in a period of political convulsion. It offers everything from Polish folk music to the sultriest Birth of the Cool-style jazz. Pawlikowski includes moments of reckless hedonism alongside scenes of exile and imprisonment. Best of all, the film has a truly wonderful performance from Joanna Kulig as Zula, the free-spirited young folk singer turned femme fatale. Kino Świat The 15 best films of 2018 8. A Star Is Born There are no two ways about it: Bradley Cooper's rock star Jackson Mane inviting Ally – a small-town waitress played by Lady Gaga – onto stage to sing her song in front of thousands of his fans is movie magic. Regardless of your stance on the film's back half and pretty maudlin ending, A Star is Born is an old-fashioned success story with an intensity that brings up the hairs on the back of your neck. Clay Enos/Warner Bros/AP The 15 best films of 2018 7. The Rider Director Chloé Zhao took a gamble casting a real-life family in this modern-day western about a cowboy named Brady Blackburn (Brady Jandreau). It pays off – this an authentic portrait of contemporary rodeo life in South Dakota. From her amateur cast she somehow coaxes performances more memorable than most pros manage in their entire careers. As moving as it is bold, The Rider also offers an all-too-rare female perspective on masculinity. Sony Pictures Classics The 15 best films of 2018 6. Leave No Trace Eight years after Winter’s Bone made a star of Jennifer Lawrence, Leave No Trace – director Debra Granik’s first feature film since then – should rightly make a star of Thomasin McKenzie too. Based on the book My Abandonment by Peter Rook, Leave No Trace is virtually a two-hander between McKenzie and Ben Foster. They play a PTSD-suffering war veteran and his daughter, who live in the forests of Oregon, fending for themselves. Even when the two are arrested and placed in government housing, the film refuses to be anything other than understated and is all the more beguiling for it. AP The 15 best films of 2018 5. The Shape of Water Loneliness can sometimes feel like your soul has been chained to the bottom of the ocean, at other times it can feel like you’re speaking a language no one else understands. Guillermo del Toro beautifully illustrates both these nuances in his Oscar-winning fantasy romance, in which a mute woman (Sally Hawkins) unexpectedly falls for a strange aquatic creature (Doug Jones), the only one who sees her as she truly wants to be seen. Theirs is a love so mystical, so overwhelming, that it can only be communicated through the language of dreams. Twentieth Century Fox The 15 best films of 2018 4. Lady Bird Lady Bird will always be close to our hearts. There are times when it feels less like a film, more like a hand tracing delicately through memories, of what it felt like to grow up, to say goodbye, and to find one's own place in the universe. Greta Gerwig’s story of a teenager, played by Saoirse Ronan, desperate to escape her hometown and seek the intellectual haven of the East Coast colleges (“where the culture is”, she argues) may be specific in its layout, but it is universal in its emotions. Moviestore/REX The 15 best films of 2018 3. You Were Never Really Here Whenever Lynne Ramsey attaches her name to a film, you know to expect something special. You Were Never Really Here marks a career-high for the British auteur, who manages to condense the violent story of a former military man searching for a stolen girl into a viciously edited 90-minute thriller. Joaquin Phoenix makes for the perfect enigmatic leading man, while Jonny Greenwood’s mechanical, piercing score adds to the decidedly eerie atmosphere. Amazon Studio The 15 best films of 2018 2. Phantom Thread Should Phantom Thread really be Daniel Day-Lewis’s final film, then the actor can retire knowing that Reynolds Woodcock ranks among his greatest roles. Day-Lewis plays the egomaniacal fashion designer with a childish whimsy, but there's also a spectral quality to him that looms in every scene. Lesley Manville’s deliciously funny Cyril and Vicky Krieps’s superbly sharp Alma offer two cunning counters to Reynolds’s growing appetite for self-destruction, making for some wonderfully heated confrontations. Paul Thomas Anderson’s direction allows each character to blossom on screen, in a film that makes for a masterful study of poisonous relationships. REX The 15 best films of 2018 1. Roma Loosely based on his own childhood, Alfonso Cuaron's follow-up to the Oscar-winning Gravity is a gorgeous piece of film-making, a quiet paean to the women who raised him. It's a neorealist masterpiece, shot in 65mm black and white, and built from detailed vignettes of domestic life in early 1970s Mexico City, a time there of great social unrest. Savour every scene: the camera takes it all in, as we follow a young Mixtec woman named Cleo (wonderful newcomer Yalitza Aparicio) who looks after a well-to-do family she comes to think of as her own. It's about love, grief and resilience: it will slay you. Netflix

Of course, we are laughing at them. They are not in on the joke. And naturally that is directed by the editors’ sleight of hand. You see what the team are up to early on when they layer Luke talking about a “great actor and a dear friend” over a clip of someone who is clearly a terrible actor.

Soon, though, the film turns into something else. It’s not just a real version of David Brent: Life on the Road, and it definitely isn’t about the music (the only Bros song we really hear is “When Will I Be Famous?” and Blur’s David Rowntree wrote the score). In the first scene, a tense altercation that escalates into hostility, we’re privy to what is clearly a very complex, painful and emotionally charged sibling relationship. From Luke talking about going for 10-mile runs when he was a child (“not because I was mad about running, because I was mad about having my own time”) to Matt’s analysis of how the pair work (“He’s a rectangle. I am a rectangle. Together we are a square… That’s a fortress”), we are given a glimpse into the psychology of an extraordinary twin relationship.

The poignancy is ramped up as we are shown how damaged the brothers are and how vulnerable to the rapacious pressures of the music industry and mercurial favour of the media. “Bros has never been something that the country has been proud of,” says Luke. “I never had a thick enough skin that it doesn’t hurt me.” They were clearly too sensitive for fame, and they’re open about how harmful the grotesqueries of celebrity and the business was for their relationship.

The climax of the film is a scene in rehearsals for their comeback tour in which Matt doesn’t listen to Luke’s suggestion and he feels ignored. It plays out the dynamic that caused Luke to leave the band in 1992 after he walked into the recording studio to see that Matt had already programmed the drums. “I thought I was a waste of space, I thought I was useless; he was perceived as the gifted one, he was the special one,” he remembers. Matt’s version? “It’s been a never-ending apology for being Matt Goss.”

The frost finally melts at the end while they’re rehearsing a song about their late mother. By that point, when Matt repeatedly can’t get the words out, the mood has shifted. We are watching two boys still grieving the person who dried their tears and held their hands when they were scared. It is utterly moving, even if the lyrics won’t win any prizes.
