Yes I love Gattaca too. Its intelligently written, stylishly done, emotionally involving, and strikes an almost perfect balance between an action-packed, exciting script and an exploration of important ideas that will get you thinking.
I think Kingpin is probably the funniest movie that the farreleys have done ("Run for the hills everybody, there's a giant shit-cloud coming" .)
Films what are underrated in my h'opinion:
The HuRABucker Proxy - My favourite Coen brothers film. See it see it see it.
The Iron Giant - one of the best animated films I've seen. Very moving.
Beautiful Girls. A stella cast and a lovely film, it hasn't got much of a story, you're just getting to know the people. When I first watched it - I didn't want it to end! I got a bit emotional when the credits rolled
