Re: Once Nolan's trilogy ends..
I think a tv series would work if it focused on dick's journey from circus acrobat to robin to nightwing. Bruce/batman would be a mentor who probably wouldn't be in every episode (like the president in the west wing). You can also introduce other members of the bat family like babs (maybe even have a cliffhanger episode based on a killing joke resulting in her becoming oracle and how that effects her relationship with dick and Bruce etc). Hopefully this idea wouldn't play out like smallville or dawsons creek...
