By sending Steve to the past, it reduced her to his love interest and erased all of the great things that had been done with the character before.
Nebula really got the short end of the stick. Instead of being given the opportunity to really go against Thanos, her past self really messes things up for her future self and the rest of the heroes.
Gamora is another woman who didn’t get a fair ending. While she’s not technically gone from the MCU entirely, Endgame did kill her in a rather gruesome way.
One of the most controversial and most hated endings of any character so far in the MCU is Steve Rogers. He’s one of the characters who is supposed to be done in the story, and many fans weren’t pleased with how things went.
Other than Steve Rogers ending, Natasha’s was the one most hated by fans. Many felt that killing the first female Avengers, and one of the only main female characters was a bad move.
