First of all, Nolan has made the greatest trilogy of all time, and while the film probably won't demand repeat viewings like The Dark Knight, it's narrative structure and beautiful photography by Pfister, make this film the superior one in the series.
Where the first movie explored fear, and the second movie chaos and anarchy, this film is based on redemption and pain, because as many people have stated, both Bane and Bruce experience pain throughout the movie.
And this is what makes Bane an interesting villain, because he is the polar opposite to Batman, but the same, as Nichy once said, 'you stare into the abyss long enough, it will stare back at you'. Bane is Batmans abyss, what he could have become if he had joined the League.
Structurally the movie fits in perfectly with the others, and this is what makes this the best trilogy of all. Everyone is dedicated to Nolans vision, from the cast, to the crew, they believe in what he has done, and this makes it better viewing for the audience.
The cast are fantastic, and the question of the ending? it's perfect, Wayne has paid his due to Gotham, and Gotham to him, after all it took away his parents, and made him unhinged. But this movie finally, shows him at peace, and the last scene confirms that this epic trilogy is over.
It's sad to think this, Nolan resurrected a franchise that went out of control, and then some, and has managed to give the movie a conclusion, that not only respects the source material, but the movie goer too.
