I think enough time has passed now..I can honestly say..
After watching the trilogy recently I can honestly say I was left wanting more. Story be damned even after TDKR it still feels as if the series was just getting truly underway. Perhaps it has to do with the continual introduction of vehicles and equipment to the series... all things considered I would want more batman films within this established universe.
I do realize we are living in a Batman rich environment with the recent films, the quality of the comics and the arkham games..hell even the Timm-verse is getting replay due to us older fans passing down the show to our kids...
