The first 1/3 of Batman Begins was my favorite part of the film, and I always thought how interesting it could be to go more into depth, but I can't see a weekly show running season after season after season of Bruce touring the world & training with various mentors not turning out to be overkill. One season max, any more and it'll go all stale-city. That, I would thoroughly enjoy. Some kind of Bat-family show would be great too, as someone above outlined - - have it centered around the core members minus Bruce (keep him reserved for special occasions), because I think Nightwing, Red Robin, Red Hood, Oracle and/or Batgirl could do a fine job carrying a show. Have the GCPD as secondary characters, Bullock, Montoya, Allen, etc. And you've got plenty of cross over potential with Arrow to have not only him show up, but Huntress & Deathstroke too. That could totally work.
