Hall of Famer
This isn't going to be another origin story is it? If it is it's getting to Spiderman territory, we don't need to see the Wayne's get gunned down in Crime Alley again.
Burton's Batman created this for the big screen, Nolan's Batman perfected it, I don't see any reason to revisit it again.
Who is the villain in this one? It would be good if they just picked one of the great comic stories and adapted as a standalone movie, from memory the Long Halloween was a good one, Hush was pretty good too - the Killing Joke wouldn't get up due to the content. Would be far better than trying to reboot the entire story again.
Its been said that The Long Halloween is an inspiration for the plot of this film. They tend not to do direct adaptations for the live action stuff or at least have not so far.
Reeves gives a great breakdown of what his ideas behind the film are here. Not spoilers but you may be able to peice some thing together but no more that what you can determine from the trailer. I have a feeling we wont see his parents murder in this one.
