What you may also want to do is get an account at
Amazon.com, rate as many movies as you can, and then check to see what they recommend for you. Their system tends to come up with some pretty good recommendations based on the data you've given them.
The same goes for Netflix, or any other movie rental service. Or you could stroll through your local Blockbuster or other movie store, and just grab something off the shelf that catches your eye.
