Counterpoint: Thor.
He blasted lightning out of his hammer, flew, didn’t require oxygen, and had godly strength. He was placed alongside:
A guy who can fly in a metal suit.
A guy without a jetpack who throws a shield
A guy who gets big and angry
A regular guy with a bow and arrow
A regular chick with a gun
At the time of this team up, Thor was still a cocky jock who had about as much character development as Captain Marvel has had to this point. But no one was concerned about Thor ruining the MCU.
Yes people hate Brie bc she's a women or she appears to be a bitch. Will I say she is my favorite actor, no. Better then Joe McHale or Aziz Ansari. However, she does a great job with Captain Marvel.
DC had the same issue that the MCU is running into. The lead shouldn't be your god killer. Maybe they do a "with all this power I failed bc I didn't play to everyone's strengths," story.
If Hulk or Thor lead, it would be the same issue. The eternals failed for the same reason. "We have a fast girl, a guy that has finger guns, and someone that kills a literal god." It felt empty and pointless from the other members view point. Imagine Hawkeye getting killed by a bullet with the Hulk, Sentry, and Dr. Strange standing next to him. You would question why he's there.
