If I'd been making these movies (we can all dream!), I would have introduced Gwen Stacy in Spiderman 2, fleshed her character out a lot so that the audience connected with her and got used to her, and then killed her off in Spiderman 3. I think it would have been great if they'd gone further with the "evil" Spidey thing, and Gwen's death could have given Peter the shock he needed to be put back on the right path, while delivering a massive emotional punch to the viewers. Gwen's death in the comics is heartbreaking and I feel it's been a real missed oppertunity to put something like this in the movies. Bryce Dallas Howard was likeable enough to have made you feel for her version of Gwen (well, I like her) and I'm always annoyed that she was so underused in the movie franchise. I hear Gwen had more scenes in the original cuts of SM3. I really hope we get to see them one day in any possible future DVD releases.
