The Amazing Spider-Man had a terrific cast, a very interesting villain, and a story and plot that I've seen done before, (in the first Spider-Man movie,) and the first time was a lot better. If you're going to repeat something, be sure to build upon it, and improve it. The only difference between this Spider-Man, and the FANTASTIC Spider-Man of Sam Raimi's design, is it's darker, (probably to compete with the ferociously powerful Dark Knight series,) it's less funny, and it's lacking a cameo by Bruce Campbell. Sam Raimi's first two Spider-Man movies had everything, and I mean EVERYTHING. Granted, I would trade Kirsten Dunst for Emma Stone any day, and the Lizard is a terrifying villain compared to the "Itsy Bitsy Spider" singing Green Goblin, but the fact remains, The Amazing Spider-Man, started off slowly, was filled with filler, and it poorly repeated a movie we saw before, and loved before. This new Spider-Man aught to have just picked up in the middle of Spider-Man's life somewhere, rather like Superman Returns, (although that movie was awful!) When Christopher Nolan gave Batman a makeover, he started from the beginning, but no other Batman movie had ever started from the beginning, and the previous Batman's were astronomically different than the one in Christopher Nolan's vision. The closest thing we had to this new Batman, was the animated series of the 90's, and even that wasn't nearly as insane as what Nolan's supplied us with.
In short, the movie was all right, the acting was fantastic, but we just didn't need this movie. It made me want to watch the other two, (but nothing will ever make me want to watch Spider-Man III again. That movie was torture.)
