i actually think "iron man" is a better "do it like this, you shitheads" movie for raimi and company to follow. ... in fact, iron man might be a better spidey movie than the 3 spidey movies! upbeat, fun, colorful, dynamic, etc.
i like that he's rethinking a vision for the fourth film, since i was not a fan of the first three, but i hope him taking cues from "dark knight" does not equate a darker, "more realistic" type of film for the spidey franchise. i don't think that'd work well for the character, or the (younger) fans.
