Comedies with PG-14 or higher ratings (Hangover FTW)...I don't like kid-friendly comedies, they usually aren't really funny. I put my comedies up to VERY high standards so it's hard to impress me with "mediocre" jokes
Action / Adventure with PG-13 or higher...I like most of 'em (around 90%) that aren't too horrible.
A few decent horror titles (like Saw or Mirrors, but kills get predictable and unexciting when you get later into the series/movie). Once in a while, I watch a drama. Usually I hate them but a good one can keep me thinking about it for a few days.
