I could go on and on about the movies that should have stopped at the original or even at part two, but nope, some greedy people decided to keep pushing it until they bombed. Here are some that make my list of the worst of the worst :
1) The NEXT Karate Kid: Part three was bad enough, but this one was just ridiculous. I love Miyagi but enough is enough.
2) Legally Blonde 2 : I loved the first one so much that I actually gave this one a chance....very disappointed that I did

.
3) Dumb and Dumberer : How could ANYONE replace the chemistry of Jim Carry and Jeff Daniels in the original? This movie is absurd. If you have not seen it, please do not waste your time.
4) Dirty Dancing (Havana Nights) : I admit I didn't watch this one, but that's only because NO ONE, I mean NO ONE, could ever replace Jennifer Grey and Patrick Swayze. As far as romance movies, it doesn't get much better than the original, and it was such a classic that even if the main stars came back, they would never be able to make another Dirty Dancing as well as the first one.
