Eh, it doesn't really bother me any. I find it interesting. Peter will be back at some point, so it's just a matter of time. Some people got really upset over it though....
this just looks like some kinda freaky-friday episode of an 80's Superhero Cartoon
where the guest character villian "builds a machine" that allows him to "switch bodies" with the main hero, and then at the end of the episode, everyone's back in their original bodies
if they'd planned on Peter leaving his body to be temporary and marketed it as a heavily-advertized "mini-series" type thing, then i'd be totally on-board with it
you know, where "the villian" entering Spiderman's body is "part 1 of 8"
and then in "Part 8" Peter gets his body back and then has to deal with the repercussions of said villian acting out of character while in Peter's body
i would have totally loved that kind of mini-series thing, but what they're doing now, according to internet articles, is that they're planning on making this last a couple of years, which to me, sounds crazy
wht i'm really objecting to is this weird sort of "permanancy" thing they're trying to do, they'll eventually have to return Peter back to his body in order to avoid completely totally alienating-the-hell-out-of their already-huge-fan-base, but they just haven't yet decided when or how yet, and that scares me
