Is anyone else actually kinda surprised that Red Hood doesn't get the same "I haven't read the comics at all" treatment from the thin blue skin crowd as The Punisher?
Too recent and hasn't been in any (theatrically-released) movies. Plus, before he became the Red Hood he was most well-known for wearing green shorts and getting his head bashed in with a crowbar, which spoils the power fantasy a bit.
Nah, he's been back since 2005, but that's still a lot more recent than the Punisher. There's also the problem that the most mainstream DC adaptations won't even touch Robin, and when they do it tends to be Dick Grayson. To get to Red hood, they'd have to introduce Dick, have him grow out of the Robin role, introduce a replacement Robin, kill him, then bring him back.
