Gosh, where to start...I mostly watch the horror genre, so hopefully someone will be able to recommend movies from other genres, but I like The Eye (they show this on IFC a lot), Audition, A Tale of Two Sisters, the original Ring (Ringu) and Ju-On, Infection. Some other more gory ones I've seen (though I didn't really care for them) are Versus and Ichi the Killer. Returner is more of an action movie, still pretty good. Oh, Uzumaki is also a wierd one. That's all I can think of for now; if I remember anymore, I'll add them in.
