I hope all the raving from DC Heads about the Flash was due to this being the reboot they needed so audiences weren’t confused with a new Superman etc.
To be honest it wasn’t a bad movie personally. There are definitely worse movies out there. I think this most likely failed as even both hardcore and casual fans know they’re rebooting the universe and Ezra’s issues were far more public than DC realized. I don’t think DC had much of a choice as all the shooting was already completed before all the crazy shit he did came out.
