LOL, I usually have to think *long and hard* about these kind of questions, but I recently saw the WORST movie EVER. EVER.
Dr. T and the Women. It was literally PAINFUL to watch, and I'm still convinced that I lost a few braincells (momentarily, of course

) as a result. It had no plot, and still makes me MAD that it wasted 90 minutes of my life!!! BAD BAD BAD!
I agree with whoever said "Fallen"--that was pretty damn horrid too! Oh, and I just saw "The Watcher" last night on pay-per-view and it sucked raw eggs too.
As for my faves, here they are: Dumb & Dumber, Almost Famous, My Fair Lady, Shakespeare in love, Sliding Doors, and any of the National Lampoon movies--like Vacation.
