Worst movies, hmmm...
Pluto Nash
Leonard, Part 6
Star Trek V
Gigli (Someone please stop Jennifer Lopez from being in movies!)
Glitter (Ditto for Mariah Carey)
Son of the Mask
Soul Plane
Super Babies
Howard the Duck
Battlefield Earth (How is Scientology still around after this piece of junk?!?)
Any Steven Seagal where they pair him with a rapper.
Anything directed by Uwe "Is it a video game, I'll make it a movie" Boll
PS - How dare you nominate ALL John Carpenter films... The Thing? The Fog (original)? Escape from New York?!? And my all time favorite guilty pleasure - Big Trouble in Little China?
