I think it could be an awesome movie.
Am I the only one who wants a Batman Beyond Movie?.
If you and I were the only people in the universe than yes.
It might be an awesome movie, the show kicked ass, but I'm just gonna go out and say this. I never understood the appeal of BB. The kid goes around fighting crime in a flying powersuit, totally disrespectful to the original batman who relied on his wits, cunning, intelligence and strength. It's not the suit it's the man.
From a business stand-point, I wouldn't count on ever seeing something like this. At the end of the day, Batman Beyond wasn't terribly successful. Likewise, it's a confusing alternate tangent timeline type thing that would just confuse people.
