What kind of hope has Spider-Man instilled in the people around him, though? Gwen's dead, he denied Harry of his blood (that scene with Spidey turning Harry down was so unnecessary; Harry would have been better off with Spidey not showing up at all), Spider-Man abandoned his city for five whole months ... What hope, exactly? That hope happens whenever Spidey feels like it? A lot of the themes and ideas in these movies are all over the place, and none of the themes are fleshed out enough. Is the movie about hope? Is it about time? Is it about loss? Is it about guilt? Is it about loneliness (with Electro's character)? The film makes nothing clear about what it wants to say, because everything is glossed over, and everything is a mess. But derpitty derpy durr ... I just "don't get it."
Typically, when someone tells me "You don't get it," then I tend to dismiss the opinion. Just so you know.
Spider-Man mourning for Gwen seemed to be very glossed over, and that takes away so much from such a big story arc (and from such an important character like Gwen). Just because the movie says it's been 5 months, that doesn't mean I believe it or feel the consequences. The movie did not sell me the aftermath of Gwen's death well enough for me to believe that there's an aftermath (because the "mourning stuff" took, like, 2 minutes in the film- very glossed over). The movie shows Captain Stacy haunting Peter throughout the movie ... Then Peter sees nothing after Gwen's death? If the movie was trying to shoehorn in some not-so-subtle "guilt theme," then the movie needed to be consistent about it. Show Captain Stacy; hell, showing Peter having similar visions of Gwen would have at least been something. All I see is that Peter visited the cemetery a lot in some quick montage while being on hiatus as Spider-Man. Before the Rhino, what was happening in New York while Spidey was gone? Did other supervillains attack the city? Did the crime rate go up? Did Peter have visions of Captain Stacy or Gwen? What happened in those 5 months as a result of Gwen dying?! The movie doesn't care to show me, so why should I care?
At the very least, with Spider-Man 3, I can easily say that the movie is about revenge versus forgiveness. I can't say what TASM2 is about, because the movie is so jumbled and messy. Sure, a lot of plotlines (like the Sandman retcon) feel extremely forced, but at least all of it fit into a single running theme.
