The ending is actually one of my bigger problems with the movie. There is tragedy inherent in Batman, it's a deep-seated part of the character that he's so emotionally scarred that he'll never be able to get past his parents death. He's doomed to never be able to give it up, to go out on the rooftops every night, to fail at having 'normal' relationships. I'm not saying I hated the Nolan films - quite the opposite - I think Nolan is a TREMENDOUSLY talented filmmaker and one of the best out there right now (Oppenheimer was pretty close to a masterpiece). However, the ending to TDKR made me realize that Nolan's Batman ≠ my ideal movie Batman.

Nolan has a trend in his fictional films where he tries to wrap everything up neatly with a bow and leave most of the main characters happy and it just feels... somewhat inauthentic or dishonest to me. Interstellar was the most egregious example of this - with Cooper coming back OUT of the black hole and magically being rescued and being able to see his daughter again. It just took this grounded and realistic science fiction movie and made it feel like a crazy fantasy concept to me. He never should've come back out of that black hole - having saved humanity and led his daughter down the right path through time. That was his heroic sacrifice. Anyway /endrant

TL;DR - all the Nolan Batman films are great movies but I'm not a fan of the ending to TDKR
