What movies should I watch next?

I would recommend watching them in genres. Like rent Alien, 2001:A Space Odyssey, and Blade Runner for a sci-fi like movie night. Then The Shining, The Departed, One Flew Over The Coo Coo's Nest, and Eternal Sunshine of the Spotless Mind for a mind-bending movie night. It would be easier to critique them that way. Just a suggestion =]
