I think Webb did an excellent job of remaking a movie that had already been made, but (with all due respect to the OP) I am at a loss as to what Webb did of any signifigance that Raimi hadn't already done.
To be clear, I'm not saying Webb was
more inventive/creative than Raimi; they were both adapting a story that had already been told many times over in visual and animated form. And I'm not trying to diss Raimi, but even after the executive meddling, I think Webb was working with the better script. Who exactly should credit for that, I've no idea, but there it is.
What, exactly, makes ASM more "modern" than SM? Aside from slightly better CGI, that is.
The modern bits of
ASM are mostly subtle and incidental, as they probably should be, but they're there: the cell phone gags, Peter talking about photoshopping, the video of Spidey that goes viral, the Stark-like futuristic holograms.
With the Raimi movies, on the other hand, you can imagine them set in the 60s, with the clothes and cars being decades older, and pretty much nothing else changing. (The genetically engineered spider, maybe, but that's about it.) In
SM2, for instance, MJ almost gets married at, what, 20? And then Peter proposes to her before he even finishes college? Very old-fashioned for contemporary New York white kids. Does he even own a computer in any of the Raimi movies? Sure, laptops were a bit pricier a decade ago, but not by
that much.
I'm not certain, but I suspect Raimi would happily have made his movies as period pieces if he could have, whereas Webb is clearly more interested in the now.
