Superior was just a bunch of gross violations of Peter's body. Otto used it to romance people, kill people, ruin Peters' relationships, and he "killed" Peter twice.
Yet then we're supposed to accept Peter just shrugging it off and not treating it like a big deal because Otto "wasn't that bad a guy."
Like, I get why Superior was popular. Slott loves writing Otto and the premise of a Supervillain trying to be a hero is fun. But there was a lot wrong with it.
