The Butler scene is still one of the dumbest things that's happened in a comic book movie. Apparently the Butler was supposed to be part of Harry's imagination and he was hallucinating the Butler, but even that sounds kinda weak because that idea sounds way more psychological than anything else we got in the series.
Kirsten Dunst I agree with. Like Fisher said, she was fine in the Spider-Man 1 but with each movie they made her look worse in worse, both looks and character-wise.
In fact, I was hoping for the moment Peter would would kick her to the curve and go to Gwen Stacy.
