I second that...I remember expecting nothing of it when I walked into the theater and being impressed.
I really liked
Crash (1995), and that didn't really get a fair shake. Though I like twisted films.
Kissed, about necrophilia, was another film no one saw due to the subject matter, but it was a really great and moving film.
A couple other movies include
Strange Days, and
Gattaca.
I just saw Zathura today, that was a fun throw away film...
