Besides the obvious entertainment value, I was so inspired and thrilled by the representations of grades of good and evil. There is no black or white for the most part in our world. But Batman proves himself worthy of true goodness by acting only in love for others by the end. How inspirational to see this in our hero. There are those who are good people (like Gordon, Rachel, Alfred, and Lucius) but behind the scenes and not called to the forefront of great things. There are those who are bad for the sake of greed - with selfish motive - but still play by some rules of decency (the mob and the corrupt law enforcement). The 3 main characters are of most interest. There is pure evil with little regard for self but to promote chaos (Joker ). Batman sees Dent as his replacement - someone in the lime light with power and goodness to see Gotham through to become a better place. Dent is good, but proves to be weak and unable to follow through with his mission. He falls short because he cannot become the selfless hero he needs to be to bring about the vision he had. He made it about himself. Batman, in the end, learns that you do the right thing for the greater good rather than care about pleasing and impressing people - or yourself. Anyone who always does the right thing will be persecuted. It's actually quite Biblical. It's something to see more than once to get all you can out of it.
