there is a couple of funny parts but to be honest its kinda boring.. he just smokes a vape the whole time and in the end of the movie nothing has really happened.. he didn't actually find anything out.. I can't really remember actually what he was trying to find out or prove... sarah silv was rad though.
I lot of the movie is him doing stand up comedy and talking about how it is going. So yeah if you aren't into that I could see why you could hate it. I agree that the ending was kinda anti climatic. Didn't find much out at all, which is kind of the funny part. The contrast between this where "nothing happens" and what happens in supersize me I think is where the humor lies.
