Gotta say, that take on the Batman Trilogy, in my opinion, speaks more to the author than the movies themselves. I didn’t interpret them that way at all. Like all superhero movies, it’s about doing the right thing despite obstacles. For Spider-Man, it’s the fact that he consistently has to put it over his love-life, the safety of Aunt May, and his studies. For Batman, it’s about believing in a city that, perhaps, has lost belief in itself. Batman’s father is a city patriarch, and his values, and the belief in the city, come from him.
As for the second installation, it’s hard for me to interpret it outside of his time, which was during the middle of the Iraq War, when the difficulty of fighting terrorism was becoming apparent. To me, it seemed to grapple with the questions brought up by that more seriously than any blockbuster I could recall. Even without that subtext, it’s an excellent movie, however, and, again, had more to do with the difficulty of heroism than a cynical view of human nature.
