Thor and Wanda Aren’t Growing As Characters
Most would say that Thor Odinson and Wanda Maximoff are not growing as characters anymore. This might seem odd, considering there have been some changes to the characters. Look at Thor who became “Fat Thor” for Avengers: Endgame, and has heavily introduced comedy into his overall character’s story arcs. Wanda, meanwhile, grew from a girl that barely understood her powers into a truly powerful witch. While these character arcs are fine, they essentially existed for hardly any time at all. Perhaps, if nothing else, they have not grown romantically at all.
Take Thor, who sort of lost touch with Jane Foster after the Dark World film. He had to not only get over her quickly but move on to do literal God things. He could move on, but right as he does, Jane comes back on Thor: Love and Thunder to become “The Mighty Thor.” Which also leads to her death, making Thor relearn or repeat the same lesson and loss. The same happens with Wanda, who loses Vision only to bring him back for the WandaVision show. He only exists in her mind, but she literally creates her own reality. She cannot get past the loss of Vision, and now once again has to get over losing him. It’s repeating for no real reason in the end.
