IMDb's top 250...

I was looking at IMDb's top 250 list for ideas about what non-documentaries to see if I have free access to on Amazon and it is a list clearly skewed by internet demographics. Really, if Inception is in the top 10 there is a problem. Given that Dark Knight (which I liked, but don't think should be so highly ranked) is #10 but Casablanca is #17, I am thinking maybe I shouldn't use as a source for movies I should see for personal edification.

On my list of things I should really watch at some point:
The Graduate
North by Northwest
American History X
One Flew Over the Cuckoo's nest
Who's Afraid of Virginia Woolf?
A Streetcar Named Desire
Soylent Green
Rebel Without a Cause
Malcolm X

Any other suggestions?

Movies that would be on this list had I not already seen them Breakfast at Tiffany's (hated it), Casablanca, Cool Hand Luke, Starwars IV-VI, Citizen Kane, The Birds, Amelie, Schindler's List, The Matrix, 25th Hour, Apocalypse Now, Blazing Saddles...
