The only person who's written a good, modern Blade story—Marc Guggenheim—has had nothing to do with this project so far. IDK if he's "too in" with DC to be a viable option, but it's odd he has not been involved it when he's the only obvious option… it's not like modern Blade has a ton of great comic book arcs.
This man is a certified nutjob 😂 I love how he's still carrying the Odd Future energy… and was that a green screen, silent Clipse cameo? 😂 Insanity…
