Fight Club was pretty good, and is one of my favorites. I watched Matrix Reloaded Saturday night, and I think that's my new favorite.
I've been told 1k corpses is just too gratuitously violent to be considered a good movie, as in killing for absolutely no reason whatsoever other than to make the movie more bloody. That's BS to me. The most violent ones are some of the Japanese Anime films. Fist of the North Star? Akira? Yeah, baby.
