Movie Recommendations

Since seeing The Last Picture Show, I started thinking about all those other great movies that I've never gotten around to seeing, like The Conversation, Midnight Cowboy, The French Connection, The Sting, Chinatown, The Elephant Man....I'm forgetting a ton. Help me fill in the gaps and make some recommendations. Since I've never had a comment on this blog, I almost assume that no one reads it, so feel free to prove me wrong.
