My wife and I saw it. I loved it and she hated it...but she didn't like Spiderman either.
The only complaints I have is that the 'comic book' effect (the boxes) were cool at first, but they quickly became annoying since it was an overused effect. The other complaint I thought the final battle was a bit cheesy and confusing.
Regarding the long story, I'm thrilled that it was just a lame movie about a monster going around destroying everything. It's about time that someone actually decided to tell a story.
I probably won't get around to seeing the movie again, but I did enjoy it.
