Coming next year from Pixar...
Alright, so, the godawful CG actually really supplemented the horror and fucked up aspect of it. Any type of genuine polish would have lessened that effect.
Some of the crudeness seemed forced (Sees corpse. Jacks off to corpse.), but not everything needs to have a meaning in order to be good.
Also, the protagonist(?) should stop standing in front of powerful fans. They'll mess up his hair.
In the end, this was an experiment. Sometimes they fail, sometimes they succeed. It doesn't matter which, though, because either way this was definitely something memorable.
Plus the cinematography and use of basic colors was pretty damn good in my opinion.
