Do You Like Sci-Fi?

I didn't realize I did until I glanced at the list provided by these guys and saw how many of the top 50 I'd read.

Here are some of the ones I recommend:

Foundation, Isaac Asimov
1984, George Orwell
Stranger in a Strange Land, Robert A. Heinlein
Fahrenheit 451, Ray Bradbury
2001: A Space Odyssey, Arthur C. Clark
Brave New World, Aldous Huxley
The Time Machine, H.G. Wells
Slaughterhouse 5, Kurt Vonnegut
Jurassic Park, Michael Crichton
Cat's Cradle, Kurt Vonnegut
Frankenstein, Mary Shelley
The Andromeda Strain, Michael Crichton
A Clockwork Orange, Anthony Burgess

What about you? Are there some on the top 50 that I really need to read? Do you have any favorites?
