Andrew Garfield and Emma Stone have chemistry that seems almost absurd. Marc Webb has gotten better at staging comic-book action and seems to have a real feel for why Spider-Man is a great and enduring character. From scene to scene, "The Amazing Spider-Man 2" is the most Spider-Man movie that Spider-Man has ever been in.
So why doesn't it feel like a movie?
In some ways, "The Amazing Spider-Man 2" is the perfect modern franchise film. I'm sure that any executive in town who sees it is going to walk away raving, and it won't matter if they like it or not. It is an exercise in franchise management, and it hits every single entry on the checklist perfectly. By the end of this film, they've done a very good job of setting up the next three or four films in the series, but at the expense of this film telling any sort of cohesive story.
