Bad movie: You walk out of the theater before the movie ends
Worse Movie: You walk out of the theater before the movie ends, but demand your money back before leaving
Worst Movie: You walk out of the theater before the movie ends, but demand your money back AND an apology from the theater manager for wasting two hours of your life before leaving

Then, there are the turkeys. These movies make "Worst Movies" look like Hollywood Blockbusters in comparison. These movies probably ended careers in Hollywood.

This list is comprised of such notorious flops as Halle Berry's Catwoman, Jennifer Lopez' Gigli, and John Travolta's Battlefield Earth.

If you didn't see any of these movies (and the movie's grosses would seem to indicate that fact), consider yourself lucky. At least you get to read about them instead of wasting 50 hours of your life watching them all.
