Honestly revamping the entire series can go any which way.
It's been like what, more than five years since the last one came out? And there are alot of little kids out there that could care less about the past movies, some haven't even SEEN the past movies, they just wanna see Spidey kick ass. And since Disney took over Marvel, and their fan base is mostly kids, and Marvel is a big interest to kids, I figured there would be SOME kind of series reset for one of the major heroes. If they weren't gonna redo Spider Man I was gonna say The Hulk series or maybe trying their hand at redoing X-Men or something or some other big name.
I'd say remaking the series is a great move on Disney's part, not only will it gross billions and probably even more than the last movies, but I'm sure there will be some attempt to tie it in with Avengers and make sure the main actor playing Spidey is financially happy with his contract. Seeing as how they made sure to keep big names for Avengers from the previous movies, not including Mark Ruffalo, I'd say it's almost a guarantee that this movie will be right behind Avengers money wise in the box office.
No matter if this movie is true to the comics, true to the characters, or what have you, kids don't pay attention to that stuff, and neither do most movie goers. As long as it's flashy and exciting, sadly, it's gonna sell like crazy. That goes for any movie.
