I think what is most people putting off isn't that Peter is dead. I'm sure almost everyone is aware that this is only temporary.
The problem is the new premise. We have a creepy old fuck in a young man's body who might get to rape the girlfriend of his arch nemesis (who he killed).
That right there is just gross and I don't wanna read about it at all..
Other replacement stories don't really compare since the replacements (like Dick Grayson, Ben Reilly or Bucky) where nice guys who hadn't forced
anything on the hero.
