I'd like a live-action Batman series, but not connected to the movies. It wouldn't be the same, and IMO I wouldn't see anyone else in the roles being occupied by the actors in Nolan's movie. I'd like a show that was based heavily from The Man Who Falls, Year One, etc.
An animated series based on the Nolanverse on Adult Swim would work for me, though.
If any character has ever earned the right to enjoy a happy retirement, it is Bruce Wayne. Nolan ought to be commended for caring enough about the character and believing enough in his own vision to provide a definitive, satisfying ending to the story of an ordinary man who turned tragedy into the motivation to accomplish something extraordinary.
