But as the show goes on, it becomes increasingly clear that Raylan is a deeply damaged individual. Beneath his super-cool exterior is a core of pure rage. He’s full of simmering resentment, and it colours his every interaction with the outside world – which is, of course, one of the things that makes him so interesting to watch, because you know that rage is always waiting just below the surface, ready to explode whenever a petty criminal pushes him too far.

And the Harlan County of Justified is absolutely rammed with petty criminals. It’s not a prosperous place, and dodgy dealings are everywhere as people use whatever means they can to get by. The show’s supporting cast is stuffed with colourful criminals of one stripe or another, but its main villain, particularly in the first season, is Boyd Crowder.

No hero, no matter how reluctant, damaged, or complicated he might be, is complete without a suitably matched nemesis. And in Boyd Crowder, Raylan gets his perfect foil. They’re complete opposites, and at the same time, they’re exactly the same. The two of them share a long and eventful personal history: they grew up together, worked in a coal mine together, and saved each other’s lives on more than one occasion, but while Raylan moved into law enforcement, Boyd went into law-breaking. The way these two characters are written and acted, you can’t help but buy into their ridiculously complex love-hate relationship.

Timothy Olyphant is, without a doubt, the star of this show – he’s effortlessly cool, magnetically attractive, and capable of conveying all kinds of complicated emotion in the way he moves – but if anyone could steal it from him, it’s Walton Goggins. No matter how despicable Boyd is (and when we first meet him, he’s is busy fire-bombing churches and preaching white supremacy to his loyal gaggle of adoring drug-addicted followers) Goggins’ performance ensures he’s never less than fascinating. Watching either of them, alone, is a delight; watching the two of them together is hypnotic. Even if every episode was just Raylan and Boyd sitting in a room talking to one another, you’d still tune in every week to avoid missing a second of it.

But Justified is more than just two characters. It’s a believable window into a whole world; almost every character that appears on this show, whether they’re a series regular or just a one-off crime-of-the-week baddie, gets enough colour and backstory to make them feel real. Although Raylan is undeniably the centre of Justified’s universe, there’s always the scope for any character to surprise you – everyone’s got layers, from Raylan’s drug-dealing father to his ex-army ranger colleague to his court stenographer ex-wife.
