For a thread about overall movie tastes, I'm seeing only horror films mentioned
Now two good black humor comedies are:
Dr. Strangelove- It has nukes, that strange Kubrick twist, and more subtle humor than you can shake a stick at.
1941- Airplanes, makes fun of the American mindset, and one unforgettable line: "HOLLYWOOD!" Also has Christopher Lee playing his exact same character in LoTR and StarWars
Hopscotch- You get to learn what FBI really stands for.
The Producers- Mel Brooks, enough said.
Yes, both of these are completely "unamerican" movies, but they're entertaining!
I also like it when a movie goes one direction and then logically flips onto it's side.
Minority Report is a good example of this, the first hour of the movie as far as I care could be burned, but then the last half hour the entire movie takes a sudden turn and is very entertaining. Sadly the rest of the movie is a slow and painful exposition leading to the plot twist and the real movie after it.
