Rollover with Jane Fonda. I don’t remember it, only that it was very boring.

Worst in terms of....? I've seen a lot of movies that were so bad they were good: Reefer Madness, Plan 9 from Outer Space, I Spit on Your Grave, Mommie Dearest, Superman IV: the Quest for Cash, Hobgoblins, Troll 2, Mac & Me, Batman & Robin, Freddy Got Fingered, Masters of the Universe, Vampire's Kiss, Master of Disguise, Catwoman, Birdemic, Disaster Movie, Epic Movie, Meet the Spartans, Fateful Findings, Saving Christmas, The Wickerman Remake with Nic Cage), or pretty much every Nic Cage movie... I found something to enjoy in each and every one. But then there are movies that seemed to simply have no Reason D'Etre - Waterworld (Just watch Mad Max and then ask yourself "what if this happened on water?" - and there you go), Aeon Flux (the animated series was great, if you're into that sort of thing - the movie was like they took everything that was not-so-good about the cartoon and made it live action, and missed the point, then tried to cram in a moral-of-the-story moment that just didn't fit the tone or the plot...), or Hollywood remake X of horrible no-budget indy/horror film Y (for example, "Night of the Living Dead" was darn near perfect, so they remade it and took out all of the subtle cultural commentary that made the original so good). But the worst movie I've ever seen was "Unhinged." Bad story, bad acting, bad directing, bad editing, boring, not worth anyone's time.

Probably "Date Movie". They don't come much more atrocious than that. Having said that, "The Blair Witch Project" was a complete cowpat of a movie as well.

There have been many. probably the stupidest though was Airforce One.

Cool World. It is an adult version of Who Framed Roger Rabbit. I don't know how that movie managed to find an audience.
