Its hard to say Im all over the place 5 movies I consider to be good ones off the top of my head would be Rushmore (well most of the Wes Anderson/Owen wilson movies) Fightclub, Clue, The Big Labowski, and Pulp Fiction
i just finished watching Congo on netflix, hahaha, what a ridiculous movie.
if you're into thrillers i suggest After.Life
Defiance is also good (i watched that earlier tonight)
The Girl with the Dragon Tattoo, The Girl Who Played with Fire, and The Girl Who Kicked the Hornets' Nest, ThanksKilling (hilariously weird low-budget comedy horror movie), The Fifth Element, any season of Weeds, Dexter, 30 Rock, Arrested Developement
....that should hold you over for a little bit, haha
district 9 (aliens and good storyline i thought)
the illutionist (makes you wonder if real or not)
league of extraordinary gentlemen ( awesome fight scenes and graphic)
harsh time ( great acting job by christian bale in my opinion maybe his best)
