I would like to see more use of the shuriken-like batarangs. Definitely need some smoke bomb action, and of course the grapple launcher. I would also like to see Batman use some simple equipment like lock picks. Not sure if the nightvision lenses built into the cowl would work in a movie, but I would like it considered. I also loved in Dark Knight that they had the cowl booby trapped, would love to see a different take on that.
"All I really need to know is this: Batman always comes back, bigger and better, shiny and new. Batman never dies. It never ends. It probably never will."
I believe in Batfleck
