We have Loki, Zemo, Pierce, kind of Bucky, [BLACKOUT]Ego[/BLACKOUT] and Cate Blanchett/Hela on the way
Plus a decent Ultron, Red Skull, Ronan, Abomination and Killian
compared to just a few true duds
Once again, imo:
MARVEL HAS NO VILLAIN PROBLEM
Disagree, disagree, disagree, disagree and DISAGREE
Ultron was a shadow of his comic self, neutered and self defeating and completely out of sync with the theme of the film, not a creation of the Avengers or a reflection of them despite the movie saying so over and over. He was a puppet with Spader's charm, and carried all the menace of such, as opposed to an uber death robot with a real sense of humor. This was one of the MCU's greatest travesties for me personally, far worse than Mandarin or whatever.
Red Skull as also neutered, not just thematically, as the removal of the Nazi elements is understandable to a degree, but this was the most impotent villain of recent CBMs other than Trevor Slattery. Not only that, but he failed to provide the hero any kind of challenge, he doesn't even have the decency to be defeated by Captain America, but grabs the cube and suicides himself after he takes a good hit.
Ronan, the judge of humanity's worthiness in 616, is turned into the least interesting genocidal maniac I've ever seen put to film. He accuses no one, because all of his character has been excised. He is a plot device every bit as galling as Malekith, simply with a cooler design. Not as neutered as Red Skull or Ultron, sure, but still... who the heck is this guy? No one knew, no one cared. Korath, with half the screen time, was a better villain, which is why his death was more satisfying.
Abomination promised so much, Captain America-ing on the Hulk without a Hulk serum, and then grown big it just became a generic knock down beat up, emphasizing the mind boggling lack of technique in not only the final fight, but in the filmmaking of the final third of the film. This is the case in point of MCU's villain problem, when the movie doesn't create an exceptionally magnetic lead, it falls apart, because the final conflict is uninteresting, because the villains are meaningless, made worse because Blonsky was meaningful during the first half of the film. Him with Hulk seemed so scary, but the result? Not really a problem. I remember Omar's cameo better than that fight.
And Killian, Killian, Killian. Killian works as a decent villain in almost any other film, but as a twist for IM3 in particular, he feels Shayamalan like. They did the whole 'no you don't get a cool new CBM-type villain, you get a boring business man' which has meaning, but they didn't have the decency to make him a boring businessman either, they went ahead with giving him a full suite of powers, and a 'costume' of sorts with his Fing Fang Foom tats. In this, he ALSO fails the themes of the film because he never brings his mind against Tony's to show Tony himself is the Iron Man, not the suit. His whole motif, being someone who is NOT mad at Tony is lost because the twist takes us back to same ol' same ol' town, just minus the CBM villain we all came to see. And on Slattery, who is always connected to discussion of Killian as a villain, no disrespect to Ben Kingsley, if they're going to twist Mandarin into a joke, why NOT cast an actual Chinese person or Chinese American? Man...
This is not to say that I didn't enjoy all of these films, but it was despite the weakness of the villains, not because of them. This is on top of the duds, which I think might outnumber the actual good villains.
Now, we could argue whether or not this is an actual problem - it doesn't really seem to be - but MCU villains regularly disappoint, because such awesome versions have existed in comics. It's a slightly less onerous version of Fox's Dr. Dooms, it's like, when it comes to villains, MCU: DO YOU EVEN COMICS, BRO?
