The worst movie I've ever seen was Waterworld, what a waste of $$$ that was!
Where do the outlaw "smokers" get their smokes from, if the polar ice-caps have melted??

I'm sorry but it does not even make sense!

What's the worst movie you have ever seen and why?

How about "Queen of Outer Space"? http://www.imdb.com/title/tt0052104/...nm_flmg_act_56
What can I say? I'm old. At least, Zsa Zsa was nice to look at in 1958.

Haven't seen it, but I saw it on a worst-movies-ever-made-screening flyer (along with "The Green Slime" and "Satan's Sadists") once.

For me, it's tied between Dog Soldiers and Carnosaur.

I'd say Battlefield Earth has to be up there. Starring John Travolta and based upon a book by L. Ron Hubbard the plot and script are truly terrible.
Then there's Left Behind about people being raptured. The whole premice and structure of the film are laughable and here I am in no way criticising christian beliefs just how poor the film represents them.

I've seen many bad movies, but "The Day After Tomorrow", "Tornado", etc., are ones of the worsts.

Also, despite being a David Lynch fan and loving obscure surreal movies, I only managed to see "Inland Empire" halfway through. I guess it speaks for itself.

I quite enjoyed those two movies as they're just mindless relaxation -- not making them good movies, of course.

I have Inland Empire on DVD, enjoy some David Lynch, but have yet to watch it. I loved Lost Highway and Mulholland Drive but just the first few minutes of Inland Empire looked terrible.

Indeed. The first half is equally terrible... Don't know about the second half, since I didn't see it . Mulholland Drive on the other hand is awesome; definitely one of my favorite movies.

There are only a few movies that I have actually walked out of. One of them was, Terms of Endearment. Never mind that all of the cast are fine, experienced actors – I simply couldn't buy-in to the story, and suddenly I felt that I was looking at actors who were reciting lines ... not the fictional characters they sought to portray. I don't fault the actors for this: I fault the screenwriter and maybe the original author.

One movie that I still like – because it is so damned awful while it takes itself so damned seriously – is Hotel Hell, the movie from 1980. ("Uh huh, the 'O' of 'HELLO' on the motel sign was sort-of burned out ... get it?") This is one of those "make a gagging sound-effect in the back of your throat, for two solid hours" movies that were so popular at the time. People get their voice-boxes ripped out of them (for some reason never quite explained), and buried up-to-their-necks in the garden (ditto). Then, of course, near the climax of the movie, someone hitches a cable to the back of his truck and runs it (off-screen gore ...) through the aforesaid garden. You get the idea. But anyway, the basic problem was that it got so absurd that I started laughing, and once I started laughing at this oh-so self-important oh-so-awful movie I just couldn't stop.

"Huh? No, I'm not a sicko. Of course I can baby-sit your kids ..."

Roger Ebert loved Motel Hell for the same reasons you didn't like it:

Last House on the left. The one in the 1970's. At the drive in. I had just watched "SuperFly" before I drove out of the local drive in outdoor theater after the first few minutes of "Last House on the Left".

the last house on the left was based on a Scandinavian movie < The Virgin Spring > . Much like the Magnificent 7 was based on the 7 Samurai.

Hey!! That was one of Siskel & Ebert's "Guilty Pleasures" (movies they were almost ashamed to admit they liked).

Brad Pitt in 7 years in Tibet.

No, sorry. La La Land was much worse.

"Natural born killers", the only movie i ever walked out on, what a piece of dross!

Killdozer, hands down.

The bulldozer showed more emotions than Clint Walker.

Batman vs. Superman.

HORRIBLE. But I watched it with friends in the theater, so I couldn't leave. Possibly seen parts of worse movies, but never finished them, so this is the worst I've ever seen start to finish.
