That's so similar tho to what we got with Batfleck.
Kilmer, Keaton - they looked great, but it was obvious the costumes were heavy and restrictive - mainly because keaton wasn't a bulky guy to begin with and hard to imagine it wasn't anything but mental rage and adrenaline getting him through.
I feel like they could go back to the begining of Batman, similar how 'the spider-man' was almost a creepy, horror comic - like the fly, where an experiment went wrong and this man with spider traits tragically tries to do good but freaks out people with his posturing and costume.... there's a few great youtube videos on this.
It could be great if the batman wasn't at all seen as heroic, but this scary, weird man going about the streets, gaining vengence etc and cleaning up the city - i feel burton tapped into that slightly but then lost it in Returns and to an extent in BvS.
Have this urban legend around gotham's rooftops that freaks people out, but what they do see of him, what the eye witness reports state is that he's this weird beast like man, creepy etc and more like a man bat than a bat man and Bruce uses theatrics as cover and instead of these heroic gargoyle poses, he's more like nosferatu up there. Instead of rippling muscles it's shadows and we just see cowl and cape a lot, lurking, it's almost like he avoids light - like true ninja's. Picture the Begins 'port scene' where he dropped down with the tone, atmospherics of the opening roof top scene of B89 with the cowl of Batfleck and eyes of Keaton... i'd like that, a lot.
