The greatest achievement of the film is its immersive atomosphere. You feel each hit whether it be orgasmic or nearly lethal, you feel complicit and guilty in Tommy’s fate and most of all you feel conflicted over Renton’s betrayal. The friendships that form the narrative, much like the skag, are addictive and dangerous but familiar. Boyle and his actors are working at the heights of their powers, and somehow manage to make the aesthetic and lifestyle of the gear heads look cool and exciting as well as terrifyingly undesirable.
