Re: Fear. Chaos. Pain. Vote for your favorite Nolan Batfilm!
It's not really a "hard" ending. Not as hard as it could have been, anyways.
This is starting to make me uncomfortable.
But anyway. Point is, even though yes, Bruce's story did get an ending, the world of the trilogy itself is still very much left open SHOULD WB choose to go that route (and I really hope they don't). I think the best CBM franchise for a real hard ending would be Superman.
