Nolan's Batman Trilogy - My understanding of his brilliance

I wrote this on a friend's FB wall as a reply but was amazed at Nolan's thinking once I put all things together. I may be wrong in some of my interpretations but only Nolan can confirm that. :P so sharing it below.
First movie had scare crow who works with league of shadows to destroy Gotham. Ra's Al Ghul is almost as powerful as Bruce Wayne but not Batman. It showcases Batman as a powerful hero who can beatup any thug from behind the mask. In second there comes a man who is unbeatable because he doesnt have a personal motto. He wants chaos.Peace disturbs him. He is physically weak but mentally unstable enough to create chaos. Second part is mainly about how most of the people "either die a hero or live long enough to become a villian" like Harvey Dent. It shatters Batman mentally because Dent shows him it's not easy to stand for what is right all the time. In third he is weak now physically from the injuries, he is weak mentally from the loss of Rachel and loss of hope that there can't be another batman. When Bane comes into picture as very powerful villain, even more powerful than himself, he is beaten and as Alfred says wants to die now. But Bane does not let him die, because his(or accomplice's) victory is in making Batman watch Gotham burn. There Batman learns his lesson, like he learned in first part. When he became batman he realized he has to conquer his fears to become powerful and instill fear in others. But he never feared death. In third part he is taught to fear death more than fearing failure. Remember his father coming to rescue him when he was a kid and saying "why do we fall Bruce?so we can learn to pick ourselves up." He learned to pick himself up from the prison hole in this part by learning to fear death which he lost after losing his parents and then Rachel. So all the antagonists in three parts made Batman what he is from an aimless rich kid who was hell bent on revenge in the beginning. Now his hope is Robin as new Batman. As per Nolan, Robin and Batman are not two people. Only problem with TDKR was the twist in the end. Bane should have been on his own with a stronger motto. In some of comics, Bane is challenged by the stories of Batman and chooses him as his opponent. But by doing so, the motto becomes similar to what Joker had. So Nolan changed it but it was not good enough. 
Nolan set his standards so high and he always sets new high with his latest. Myself or anybody are not qualified to say he did not reach his standard in this. Its definitely not a bad movie. The only debatable point is the magnitude of the greatness of the movie.
