I don't know if we can be friends if you don't like the following movies:

Pretty Woman (watching it now, forgot how awesome it is)
Taxi Driver
The Graduate
Citizen Kane
Garden State

That's all for now. I can never remember my favorite movies when it matters. I also like the sese movies, but I still like you even if you don't like them:

Adaptation
Lost in Translation
Eternal Sunshine of the Spotless Mind (might be on the first list)
Memento
Magnolia
Amelie (seriously, who doesn't like this movie?)
Napolean Dynamite
All the Thin Man movies
