The Batman. I want to see along the lines of "Murder She Wrote, Columbo, mixed in with a gritty cop drama a al NYPD Blue, and these CSI shows. Due to budgetary constraints my vision as a Batman show would have to focus in on the Batman's skills as the "world's greatest detective." As with the Nolan films, the superhero aspects would be a secondary role.
Bats would basically go after the corrupt elements in Gotham, Commissioner Loeb, the Mayor of Gotham and the Roman. It wouldn't just be The Batman, Captain Gordon, and Harvey Dent would be a part of "his crime figthing team." The first season would expound upon Year One and just as Year One ended with The Joker, I would bring J in towards the end of the first season. The show would have new characters (such as a serial killer/and or rapists, and other DC characters. I would also find a away to incoporate Dick, Jason, Tim, and Damien into the show.
Another good idea for a Batman show is and origins show a la Smallville. It would show a young Bruce Wayne travelling the world to seek out the masters in certain areas of expertise to learn their skills to aid Bruce in his war against crime. The series would end at Year One.
