""Spider-Man 3" is, in short, a mess. Too many villains, too many pale plot strands, too many romantic misunderstandings, too many conversations, too many street crowds looking high into the air and shouting "oooh!" this way, then swiveling and shouting "aaah!" that way. And saints deliver us from another dinner date like the one where Peter plans to propose to Mary Jane. You know a movie is in trouble when the climactic romantic scene of the entire series is stolen by the waiter (Bruce Campbell)."
