Nah. I have faith in Gunn. He has three things going for him: 1.) seeing where the DCEU screwed up, 2.)
seeing where the MCU screwed up, and 3.) being vocal about how much he loves the DCAU and Reeve Superman. The way I see it, Paul Dini, Alan Burnett, Dwayne McDuffie, Bruce Timm, and all those DCAU guys created the perfect blueprint with The Animated Series, JL, JLU, etc. and Gunn has been hitting all the right beats for me, personally, in talking the talk when it comes to understanding these characters. Whether he can walk the walk is another matter entirely, but I’m confident.
