One thing that I'm now wondering...is The Batman II going to be a DC Studios film or not? The lack of the WB shield before Superman was surprising to me in that they're really committing to making that a totally separate brand. But given that, it might be confusing to do the same branding for a project that's not supposed to be a part of that universe which all other upcoming projects with that branding will be. I guess we can assume it is, if Gunn is the one who's going to (presumably) be giving notes on it.
It's a weird dynamic. Also, I've liked pretty much all the comic book films that Gunn has made (iffy on TSS), but when it comes to his own tastes in the genre based on things he's said about other films...I often strongly disagree lol. He's bashed both the Burton and Nolan films in the past, and then called The Flash one of the best superhero films of all time. That's a big oof in my book! I kind of wish I didn't know that the guy running DC for the foreseeable future holds those kinds of opinions. I find Gunn occasionally insufferable, but then also disarmingly honest to a fault which can also be refreshing... ultimately undeniably talented at his craft and realizing his own visions. Saw Superman a second time this weekend and while I think it's certainly not perfect, it definitely works and does kind of exactly what it needed to do. He actually cracked a modern, bright and optimistic Superman film. No small feat.
Anyhow, all this to say that I find it a bit strange that James Gunn of all people is the guy holding the red pen in this scenario when Matt Reeves has also already proven himself as an accomplished filmmaker. But given Gunn's strong public support for Reeves in general, you have to imagine that any feedback will be constructive and supportive and not getting in the way.
