With two No. 1 albums, a sold-out arena tour, and recognition coming from the United Nations, Nicki Minaj, and everyone in between, BTS is capping off an extraordinary 2018. Luckily for people still wondering how the seven-member South Korean boy band got this huge, the group's movie-theater debut Burn the Stage: The Movie takes a step back to see how it all came together. The explanation is much deeper than swoon-worthy looks or tight dance moves, but instead, their music connecting fans (known as the ARMY) from all over the world and the member's devotion to their craft.

Originally developed as an exclusive series for YouTube Red, Burn the Stage takes an inside look at RM, Jin, Suga, J-Hope, Jimin, V and Jung Kook's lives on the 2017 Wings Tour, a voyage which included their first arena shows in America. After reconfiguring a bit of the storytelling, plugging in new interviews, and adding some of BTS's milestones from this past year, Burn the Stage: The Movie not only honks up the boys' accomplishments since the Wings Tour, but also explores deeper as to why this is all happening, how the band is handling their meteoric rise, and their balancing act between being pop idols and humans.

The film starts with a humble BTS preparing for their 2017 trek, hoping to successfully pull off the five arena dates in America—a stat that some fans might giggle at given this year's Love Yourself Tour more than doubled that amount of shows with even larger venues. BTS have high expectations of themselves as performers, seen through the movie moments fans weren't previously privy to like RM dancing through leg injuries or Jimin detaching himself from the group after feeling he failed to perform at his best. Viewers get insight into the guys working on music in their hotel rooms, practicing speeches in the local language (RM pushes himself to find better words for a speech during a Japanese concert since he didn't want it to be "too scripted"), and becoming so ingrained in their performances that they memorize their bandmates' cues and moves. These are the ways BTS communicates around the world—it's what they call "the language we know: music."

This harks back to why the K-pop superheroes are even in a position to hold arena concerts in America—the music. The fans connected with and followed this band due to their music and experiencing that with the artists is what fills up these huge venues with performance and audience interaction heightening those experiences. At one point, the group reflects on how they sometimes wouldn't make eye contact with the audience in the past, but now can look to concertgoers and see the joy they bring to them.

Fans will be happy to see that despite such dedicated passion, BTS is now at a place to enjoy themselves too. A section of the film throws back to the septet's debut days where vintage clips of a very-young BTS share hopes for their careers and freak out over winning new-artist awards. But whether it's moments where the guys are chilling at the hotel, BBQing at a pool party, or savoring downtime with one another backstage, BTS are almost always enjoying themselves alongside their hyper-focused-sometimes-tortured dedication to their art.
