Worst movies you have ever seen.

I've never understood the point of 'worst' lists. They're really unhelpful for anything, and it's much better to think about things you enjoyed than thing you didn't. Also, your 'worst' is just 'least liked'. It's most often just your taste, not that the movie itself is bad.

But if you insist, the only movie I ever left in the middle at a cinema was "Drowning by Numbers". And again, just not my thing. Apparently quite a few people enjoyed it.

Probably Melancholia. Pretentious and inconclusive.

Super Mario Bros. from 1993

Enemy (2013)

Had to look up the name on imdb cos I only remembered it had time in the title.
In Time (2011)
It's awful, caught it on TV and watched it untill the end just to see if there was a point to it. The best I could figure out was that they probably wrote down a note reading "time is money, literally" and somehow got the greenlight for making it from a studio. The world building is abismal, the characters have no depth or personality, and the message is so on the nose and the ideas are barelly explored or explained. I honestly wonder if they even had a script before they started filming or just made it all up as they went.

Worst I've ever seen? Tough choice. But recently, Mandy (2018), or at least the first half of the movie.

Anything made by The Asylum :) My pick would be: "2012 Doomsday".

Postal.Showed to somebody that wanted to be a movie director because:"If they can find funding to create this you should be ok in your career".

If those are the worst movies you've seen, then man, you need to watch more movies! Well, I can't speak for "Adam and Eve vs the Cannibals", as that's a movie I'm not familiar with, but even if the movies mentioned in the original post might not be masterpieces, they're at least working movies, with some form of structure, not awful special effects, acting that's more than functional and so on.

Try watching something by The Asylum, like Snakes on a Train, Transmorphers, Alien vs. Hunter and so on. That's a good start for bad movies. Or a terrible start, those movies are not even good for a "bad movie night" with friends. You can also throw in something like Star Wars Holiday Special, which Lucas himself have said that if he could, he would seek out every single copy of and destroy with a sledge hammer. It's embarrassing and annoying Even the famously awful movie "The Room" is in many ways better than the movies I mentioned (The Room is baffling in all its bad choices, but at least it's entertaining)

Tokyo Gore Police

'nuff said.

The ones I can think of now, are Ready Player One and Dredd. Possibly because they were sold to me as "dystopian" movies while they are fully embracing a dystopia rather than being critical about it. I couldn't even finish Dredd.

I agree on Avatar. And Ghostbusters 2016, which I didn't bother to watch. Your 2 others I don't know at all.

Ghostbusters 2016, Predator 2018, Alien: Covenant

Hellboy 2019 for laughs and fun!
God it was more awful than I expected.....

All these movies got a rating of 3/10 or lower from me.

"Blair witch 2" and "Lost in Translation" despite it's good reviews

Mandy
The Transporter
XXX
Fifty Shades of Grey
Dumb and Dumber to
Zoolander 2
..I think the last two seemed worse because I found the originals very funny.

Deep in the woods (2000)
Just very bad

Son of the mask

There are so many movies worse than Avatar or Ghosbusters, you should watch more movies.

Gigli
House of the Dead and basically every movie from Uwe Boll
Son of the Mask
Dumb and Dumberer
Battlefield Earth (I've seen this one in theater, that was painful)
Rollerball (this movie sent John McTiernan in jail)
Catwoman
Batman and Robin

Now i have a long list of movies to watch.

While Avatar is obviously terribly overrated, I definitely wouldn't call the worst movie I've seen: it's a well-crafted amusement ride, nothing more, nothing less. I'd place it somewhere with Marvel hits.

I tend to be picky nowadays, but yeah, I've watched my share of trash in my youth (like American Pie, Scary Movie or whatever was popular among kids in the late 90's - early 2000's). As for the last few years though, the absolutely worst one was probably Assassin's Creed (a brilliant example of a movie that can't be saved even by a high concentration of truly gifted actors).

I was quite impressed with the circular polarised 3D technology introduced with Avatar and thought the 3D effects were well implemented there. I thought the story was nothing to write home about, being pretty formulaic, and I don't know what were they thinking when they named the ore Unobtanium, but I still enjoyed the experience overall. It's not something I'd want to watch again but I thought it was much better than movies like Independence Day (an alien ship had a flight control system able to be intuitively piloted by a human, and an operating system and i/o port compatible with contemporary American systems - was it running Windows 95?) and John Wick (nice cinematography and costume design but poor acting, childish or absent writing and disappointing fight choreography, plus the car advertising/product placement was a bit too blatant).
Edit: I think I found an old interview with the screenwriter for John Wick:

Ace Ventura 3, never was I dissapointed by a movie this much
