Anyone who has followed the SpiderMan movies probably knew that the third wouldn't be able to keep up the pace set by the first two. Spider Man 2 was even better in some ways than the first, and while it would nearly be impossible to top that in a second sequel, Spider Man 3 had to be done. All of that said, I was inclined to be forgiving in watching Spidy 3, which was a good thing.
Although it was fun and entertaining, the third Spider Man has gotten away from Spidy's dry humor and witty repartee, and has become just a good superhero/action movie. I like these, and you will too probably. It is certainly busy with plot, fight scenes, and bad guys: Gwen Stacey is introduced, becomes MJ's 'rival' of sorts for SpiderMan, who is already busy fighting Hobgoblin, Sandman, and Venom. It's nothing if not a vigourous workout for our hero! And well worth the purchase price (check the Amazon.com vs. .ca prices!).
Spiderman 3 also manages to convey some important, if simply spun, messages about forgiveness and letting go of the past--something that gets harder but more important to do as we age. And perhaps that's what the Spider Man movie franchise should consider, before it too becomes stuck in recycling past conflicts---please, Marvel, think of something else for Spidy 4 other than Spiderman vs. Rhino, Electro, or the Lizard...etc.!
