I guess here's my thought process - and I don't want to compare films, but I will - and I'll try to do it in a respectful way so as to not insult anyone.
The more you make the story revolve around the character himself and how his decisions effect the lives of everyone he cares about and everyone surrounding him, then the more you audience is going to be invested in that character when the film ends. If you make it about how Peter got to the place in his life where he becomes Spider Man, and then walk that road with him as he continues to develop himself into the hero he becomes, then the audience reacts to that and cares more about the story you're trying to tell with the few hours you have on screen.
This is something I think that drew me initially to Batman Begins, because at it's core - the film was really all about the origin of Batman to begin with, right? 2 1/2 hours worth. And it was done really well, I've always thought that. From the casting (with 1 exception, don't ask who) to the story, the pacing, everything was really well put together.
And that's why I'm so drawn to this version of Spidey that's being released - because from the casting, to the writing, and the possible story development - it feels like it could be the 'Begins' for the Spiderman franchise, and that's a pretty exciting thing for anyone who has been a fan of Spidey as long as I have (and some of you, Im sure).
Not trying to start anything here, I just think that if it's done really well - even a rehash of the origin of the character can be extremely rewarding and be the type of Spiderman film that fans have been waiting on for a long time.
So again, I'll be going to see it - regardless of what the hell RT scores it at, and I'll make the judgement myself. Simply because I think I owe the franchise that much, at least, and completely ignoring the fact that I'm pretty stoked for it.
Headed home from work now, be around in a bit I think. Be nice to each other, will ya!
