It's interesting that every critic's opinion of this films seems to count except for Lucas'...even though he's dead on about his assessment of the film. The film, to put it bluntly, is a complete mess at the script level. And it becomes unintentionally silly because of it.

Say what you want about the Prequels but they are no where near the mess that Spider-Man 3 is, at the script level. I mean, it's just plain bad on a lot of serious levels...things that should've been caught before this film even started shooting.
