"Heaven's Gate" is certainly dreadful. It's got competition for the worst film ever, but it is by far the worst film ever produced by a major studio with a multi-million dollar budget, an all-star cast, and an Oscar-winning director. Ended his career PDQ, I'm not even sure watching it on Mystery Science Theater would help.

While I can't say it's the worst film I ever seen "Terms of Endearment" is the only movie I have ever walked out on. Ridiculous, unsympathetic characters, plot lines too silly even for soap operas, and the idiotic idea that someone would get stoned and then listen to Broadway show tunes, and then, of course, the 'tear-jerking' death of the Deborah Winger character which is simply unbelievable (my first wife managed to stay for the whole thing and she told me what I can only describe as incredibly predictable plot events.) The only move where I can say that mysterious, masked gunmen suddenly appearing and slaughtering the main characters would still have failed to make the movie interesting. Absolutely loathe it.

The dishonor for worst film I tried to watch belongs to the horrifying "Death to Smoochie" My wife and I rented "Death to Smoochie" because it had Robin Williams in it. The only unfunny "comedy" he ever made. We stopped watching the DVD after about twenty minutes. So while I didn't finish it, technically I didn't walk out on it. Positively wretched.

I should note I also stopped watching Anthony Hopkins' "Slipstream" mainly because it was incomprehensible. And that's the good part about it.
