As a result there is a lot that we assume which doesn't play through, and vice versa, and there is the feeling of not wholly knowing what is real and what is not. In this narrative we get close to JP's mind – which is scatty to say the least. The film does this very well; it doesn't push it too far so that the exaggeration takes hold, but it keeps in it the realm of reality. The performance from Garrett adds to this. He gets the sportsman lingo and mentality, but he is also convincing confused at times – zoning out being something he does very well here.
The narrative perhaps brings too much together on one night to really be satisfyingly insightful, but it still works despite this and produces a real sense of character which drives it through everything else.
