After that long talk he gives Blake about "anyone could be Batman, it's the mask not the man," etc., I coulda SWORN he'd be the new Batman during Bruce's absence. It'd imply a world in which Batman can continue to exist even as Bruce finds peace. Totally underlines the point about the Batman mythology.

Instead, the tease tried to be cute about something fans know. I thought they had a dynamite ending about the mythology of heroes and how they live on... and made it too cutesy. At least for my personal tastes.
