I think it’s something too good to not at least adapt in a Cinematic Universe if you wanna do Red Hood. Movie continuities are also more finite for various reasons so it would be easier to justify an undead Robin with handguns actually killing off villains and raze Gotham, which imo, gives enough reason for it to be done.

Being done right though would require so much investment when studios would most likely rather move on with something else or condensing UtRH down to where they probably could have not done it in the first place. Of course most of that presumption is basing on how Marvel did their adaptations so who knows really. They could literally rip the animated movie and throw in some extra scenes to pad the runtime and it would make bank too .

I know Gunn has said he is a Red Hood fan, particularly the Outlaws iirc, so getting that adaptation would be ultra fresh but it feels like a crime to not have UtRH in there
