I also love both of these movies. However, I feel compelled to vote for Spider-Man 2. It's just such a strong film. And to those who keep complaining about Doc Ock not being pure evil, who cares? I know they overdid the "villain with a heart" thing in Number 3, but in this one it was just right. Alfred Molina was a terrific Octavious. It would not make any sense for Dock Ock to go from well-intentioned scientist one minute to crazed evil madman the next. His transformation fits perfectly into the film's theme, which is "finding the true hero within". How many movies do you actually have an antagonist who truly earns his redemption? There are plenty of characters who see the error of their and then die, but here, here Octavius shows that he is still a good man, who still has the heart to do right by humanity, and sacrifices himself, and dies at the hands of his own creation, much like Frankenstein and his monster. The third film may have ruined it a little, but if you watch the second one on it's own, and consider it on it's own, you realize how deep the film really is. It also helps to have top notch, Oscar-Winning effects (3 of them, if I'm not mistaken), a majestic and powerful score from the always fantastic Danny Elfman, and a wonderous supporting cast. I don't care how cheesy he was in the third, in Spider-Man 2, James Franco is in his form. He's sleezy, slightly unhinged, and still angered and haunted by his father's memory. And of course, how can we forget J.K. Simmons? I swear, the man was born to play J. Jonah Jameson.
Despite the fact that Anchorman is a very entertaining, silly comedy (one of my favorites, mind you), it simply is not nearly the movie that Spider-Man 2 is.
