Nah, that's actually really bad news tbh. These early reactions are all by fat virgins who probably have 10000 comic books filling up half their house, and the fact that most of the reactions are "mixed" isn't a good sign. I remember Green Lantern getting some good early reaction and we saw how that turned out. BVS got some brilliant early reactions if I recall and that ended u with 27%; hell even Suicide Squad I'm sure these early social media reviews were pretty good.
Critics are gonna trash this hard and fast, it won't be pretty. But what the fans think and the $$$ is the most important thing
