I will admit, when I started the film I really did enjoy the first 30 or so minutes.
The acting and the cinematography was really good, as was the humor and imagery.
Unfortunately, after an hour or so the humor dissipated and the story took a straight faced and awkward turn full of gluttony, yelling, vomiting, excessive language, weird sexual encounters, and just a lot of filth (literally and figuratively). Admittedly, the acting was quite good but at what cost? All of the characters were very unlikable.. By the end of the film it merely felt pretentious, gross, whiny, and boring.
Weirdness and taboos don't bother me in movies at all. What bothers me is when it's handled in such an uneven way.
