Underrated Horror and Comedy movie list?

I'll give you name of a movie that is uncensored and forbidden in many countries: "Serbian film". It will give whole different meaning to word sick and demented. The other one is "Haute tension".If you didnt watch Hostel too. It's, lets say it this way, "different" than anything else. Bloody and gory. As for the comedies, I cant help you with that one, not really a fan of them. Wrong turn 2 is the sh*tiest sh*t ever.
