I normally hate movies with a lot of sex, violence, or extreme emotional distress, but none of that bothered me with this movie because it was presented in such a detached way. It was like: If you just look at getting shot by the police, or abortions, or filthy sex hotels, from the perspective of a Terrence McKenna psycho-naut, it won't really bother you. I also like movies that are genuinely stylistically inventive in a way that seems hard to do. (This is also why I liked Scott Pilgrim. Not for the video game fighting stuff, but the little things it did especially towards the beginning, with people walking through doors and so on.)
It helps that I'm a Coil fan, and though Coil was only played during the DMT scene, the entire movie seemed like a distillation of their later aesthetic.
