For the love of fuck. No. No. No No. No. They need to make it as violent and dark and gritty as possible. Maybe slightly Nolanised but with an 19 certificate. DD is a character who has been shat on so much that it's become kinda a running joke in comics. His mother left him as a kid, his father was a violent asshole, he was bullied as a kid, his father was killed before him, he lost his eye sight, his gf died and for a comic book character stayed dead, his on/off girlfriend keeps trying to kill him, she keeps dieing and comes back to kill him, his wife killed someone and went batshit insane, one of the most productive relationships he had was with a woman he had an affair with, his secret identity is well, not so secret, have i missed anything not to spoilerific out?
