Thoughts (with spoilers):
I see this as a fascinating, poignant study of two people who are so not good for each other and keep pulling each other down.
There's an almost primal attraction between Nige and Deano- the blood oaths, the tooth necklace - but it's the worst thing for them. Gav, the roommate, a self-made, self-improving guy, is from similar circumstances, but managed to think his way out of bad situations. And he could be a way out for Nigel and Deano - even Deano starts to respond to Gav's positivity. But it's like Shakespeare or a Greek tragedy in its raunchy, farcical way - both Deano and Nigel have fatal flaws that lead to their undoing. With Nigel straightening his hair and dreaming of visiting Shepherd's Bush, he's trying to rebel again Deano, but he'll never make the break. And in a way, it's crushing Deano just as much having Nigel on a leash when he won't act on his love for him. More complex that it seems.
