For some reason I've just never liked Spider-Man. He comes off as a whiney, ignorant child that never seems to grow up or mature despite everything he goes through. I love a good coming of age story, but he just never seems to become an adult.
Don't hate spiderman. Hate the writers roughly since 2000 that only let him have a break from misery when he's in an alternate universe where he never became spider man.
Having been introduced to Spider-Man through comic books, I always disliked him. And the comics came out well prior to the 2000s. I always just found him obnoxious.
To be fair the comics do him much worse, he kills his first girlfriend trying to save her, he kills his wife with his radioactive sperm, he's the ultimate tragic hero.
However I don't think that's what OP is talking about, I think he's talking about how it keeps getting rebooted so Peter Parker never grows old, he's forever a teenager. In the comics it took time, but he did eventually become an adult, during the Civil War he's an adult for example.
