I like thriller. and ONLY thriller. Comedies are okay, but I NEVER crack a smile during the whole thing.
Horror- they're annoying because I only watch movies with my friends, and I hate how they cry loudly halfway through. -.- But other than that, yeah. They're awesome.
Action- Just too dramatic. Even action movies need a brake from all that hero-y stuff, right!?
Violent- Is it just me, or is everything too dull/cheesy in those movies?
