Hmmm. I don't enjoy Civil War because everyone acts ooc. Neither Tony or Steve would do or say the things they did in that movie based on what we know about them from other films. The whole point of that movie is so we could have that big cinematic clash at the end and it shows. The buildup is sloppy and Tony being incapable of coherent thought surrounding what Bucky did while he was brainwashed is poorly executed.
And Steve, Spartan Girl, you nailed every issue I have with Steve's "happy ending" in Endgame. Steve would never choose to abandon Bucky, the avengers, and his responsibility to go play house with Peggy knowing full well that she lived a happy, full life without him. Knowing that Bucky was being tortured by Hydra, knowing that Shield was really Hydra.
They ruined his character, I would have preferred that he had died in the fight than what we were given. I too have to pretend that the last ten minutes of Endgame were a fever dream. Thank God for fanfiction.
