Oh yes, some good ones that you all have come up with I should have on my list.
Memento - Very complex story. Loved it.
Pulp Fiction - Funny and Disturbing - I've been looking for a wallet like that
When Harry Met Sally - Very New York, and great music
Better Off Dead - "2 dollars!"
Superman 1 & 2 - Classic (although any after that go on the hate list)
Heat - Pacino and De Niro? Can't go wrong there.
:edit: High Fidelity made it's tv debut on Comedy Central tonight - not as good with all the profanity, etc. censored out.
