I think my only major sore spot with the MCU right now (that I can think of off the top of my head) is the erasure of Uncle Ben. I know that story’s been told a hundred times already, but I don’t necessarily want the origin story, I just want a little acknowledgement that Peter already had a father figure before Tony came along.
It’s the same little sting I get when people erase Owen and Beru from Luke Skywalker’s story, I guess. Just… I suppose want a little more love for the people who were thrown unexpectedly into parenthood, didn’t have money or power, and loved their kid and raised him well anyway. Those folks always get forgotten, you know?
