The main storyline, the acting, the production etc. It is all great, no doubt about that. For me personally i just don't need all the unnecessary sick, gross and weird scenes they had to put in here and there. It feels like they are supposed to be funny but it just doesn't work for me at all. Had they removed those and focused on the rest it would have been really good - a matter of personal opinion i am sure. Some might find that stuff funny. Also, forget about scenes that try to make me sympathize with a person who has already revealed himself to be a total dick... that is just wasted minutes.
