EDIT: That said I don't quite get the Raimi bashing. The first two Spiderman films are easily some of the greatest this genre has seen. Spiderman 2, IMO, is the only comic film that can even stand next to TDK. Spiderman 3 was pretty bad, but there was alot of other factors then just Raimi. Also, no ones perfect. I've never understood turning on people for one bad film. Then again, I've never understood starting a hissy fit over wings not being on someone's head, so what do I know?
This is how I've viewed it. I've enjoyed all of Raimi's films. I thought, as movies, they were good. SM2 was very, very good. However, as an adaptation of one of my favorite characters...it wasn't that great.
I didn't like the overuse of corny humor, the absence of Spider-man's personality, the complete and utter butchering of Mary Jane's character, turning Doc Ock into a "good guy" at heart, the under-use of the supporting cast, and the fact that Spider-man couldn't keep his friggin mask on.
It just wasn't my cup of tea. I think a better movie can be made that's truer to the character I know and love.
Now, that said, do I think Raimi sucks? Heck no. The guy did a lot of things pretty darn well. The train fight scene is still easily the best action sequence in a Superhero film to date. The sense of desperation and overwhelming pressure Pete felt from Spidey and life was perfect as well. But again, I've just never been a fan of how Raimi handled the characters.
Now, the funny thing is, five years ago when I said this I was torn apart, after SM3 there are tons of people who share my opinion. I do feel for the guy, because I was one of the few who thought SM3 wasn't nearly as bad as everyone made it out to be. I actually enjoyed it. But that was because I didn't like SM2 (I was actually quite disappointed in the theatre when I watched it). So when I went in to watch SM3, I didn't have high expectations. I knew it wouldn't have the things I wanted. So I just relaxed and spent a night at the cinema. And you know what? I enjoyed myself. Sure, it wasn't great, but it certainly wasn't a Batman and Robin, Ghost Rider, or even Fantasic Four.
