You wish this was going to play out like Buffy, OP, then there'd be a chance of a good flick. But the studios want stacks of dollar bills, and I can't blame them when the seventh art is so beleaguered. So we'll get an anodyne affair with no attendant spider bite, and the CGI Spidey bouncing about the urban corridors of NYC will remain unconvincing at best.
But as much as we might decry the venal motivations of studio execs, this seems more than a case of accumulating lucre. After all, Spiderman 3 did make shiploaRAB of lolly, and in order to keep the mojo going Sony could've just let Raimi continue to have his way. Alas, folks with coats with 100-dollar bill padding fancied themselves visionaries during the negotiations, and insisted that the ungodly mess of the third film not be repeated. Me, I liked the threequel (!), but respect the consensus that it was rubbish, and even those whose job it is to disinterestedly spool money found themselves taking a stand.
