There were a few things I really liked about this film especially the fact that Peter wasn't immediately an expert on his spider-powers to the point where his spider-sense was erratic and helpful but not to the point we saw Tobey all of sudden have it in his films. I also liked the constant showing of Peter using his science skills even in defeating the Lizard that was besting him almost every time. The lizard besting him every time was great too as it would have been unbelievable for Parker as he was in the film to suddenly be the master fighter.
I didn't like the ending though, not the ending of the arc mind you the actual ending. I know the Spider-Man swinging montage is almost expected and I saw it in 2D but knew that the webbing was made for the 3D folks but I thought the film would have been much more awesome if Peter says his line and it just ended, that they didn't resort to the "cheap" superhero doing classic poses that has been done before.
