The top 20 Marvel Cinematic Universe villains, ranked from worst to best

The biggest problem with the Marvel Cinematic Universe is its villains.

"Black Panther" has been praised for having one of the best villains in the universe (and in movie history). Loki, who fluctuates loyalty so often it's hard to keep up, is another great example.

But many of the other villains aren't exactly compelling. There's not much there in terms of the motives, goals, and overall, a lot of them don't feel like a genuine threat to our heroes. But that doesn't mean that all of these MCU villains are bad: they're just forgettable, even in some of the best movies to date including "Iron Man 3," "Ant-Man," and "Captain America: Civil War."

Still, there are a few gems in there, and we took a look at the top 20 to give you a sense of which were the best.

This list doesn't include all villains in the MCU: just major ones with some very special exceptions (Jeff Goldblum). It also excludes Winter Soldier/Bucky Barnes and Nebula, who are good now and it was kind of obvious they would be eventually.
