Spider-Man 3...It has everything I expected and more. Too much more. More bad guys, more fights in mid-air, more tears, more sub-plots, and more sad shots of Spidey and MJ than the first two Spider-Man movies put together.
I think this movie suffers from the same things that bother me about most movies of this genre: the story serves the technical effects (rather than the other way around), and the actors are there mostly to fill the space between computer-animated action sequences. I thought Spider-Man I and II were less that way than this one, and I loved them. I was glad when this one was over. Except for Kirsten Dunst and Tobey Maguire, who were very good, the acting was ho-hum and at times really bad.
Nevertheless, there were some interesting moments from a theological perspective. Peter Parker gets taken over by Venom, a weird alien parasite that, a la Star Wars, pulls him over to the "dark side." To rid himself of it he goes to a church, and there's a neat shot of the steeple with a cross at the top that suggests his only recourse is to cry out with Paul, "What a wretched man I am! Who will rescue me from this body of death?!" (Romans 7:24) This black, slimy creature moves from person to person and place to place with subtlety and strength -- a perfect illustration of Satan, who delights in destroying people and relationships and turning that which is good into evil.
Rather than give away more of the plot, I'll just say I give Spider-Man 3 a B-. Maybe you'll like it more than I did.
