At least in regards to the Spiderman sequel, it was just obnoxious how it seemed he was propped up as this perfect character while Peter was dumped on in almost every part of the game. Making 2 games and already dumping on the first protagonist to the point the sequel ends with them basically saying the new protagonist would do a better job than them, and that they're more or less retiring, is annoying.
Like, let Peter be a character at least for a little while before immediately throwing him into the dumpster in the most aggressive way possible.
Also, the suit Miles gets later in the game is atrocious. The exposed hair, when the entire point of the suit is to protect your fucking identity, is retarded. Not to mention the outright tennis shoes he's wearing. I get that Peter's suit also has bits on the feet that make them look more like sneakers or something, but it seriously looks like Miles just threw on some shoes he grabbed from a mall somewhere, then called it an "upgrade".
Miles isn't an outright bad character, but his implementation and way it coincides with Peter being dumped on constantly brings about a lot of resentment. It's tough introducing a new protagonist to, essentially, replace the old. Even tougher when you're doing it in the second fucking game in a series. So the way they handled it is atrocious.
