This is not a superhero movie. It's a movie with a superhero as a main character, but it's not a superhero movie. The story isn't about Bruce Wayne struggling with being Batman or duking it out with the Joker or Two Face--there are instances of these things, but they don't comprise the story. This is the story of Gotham, struggling to rise above the crime and corruption that was killing it until Batman came along. It is a movie about a city trying to reform itself and coming near destruction in the process. And it is the story of one man sacrificing everything so that it might survive and become more than it has been.
It is, in case you hadn't figured this out, a damn good movie.
