No, WB has decided the only way to make DC films is to change the stories and ignore the best aspects of the character. They basically reduced the Flash to comic relief in Justice League. This will also suck. WB lacks the person in authority that cares for and respects the source material the way Disney has Feige in charge of the MCU.
It's really sad. Flashpoint is the perfect way to reset the DCU films.
Reset? I know they need it really, but it would be a disaster. I would just try and right the ship by making good movies going forward I suppose. Which of course they are not going to do either of those, so let's hope the MCU remains solid.
I would just re-center the DCEU on Wonderwoman, Aquaman, then add a cosmic element with the Green Lantern. Focus on that for a bit.
I wish they'd throw in Timm and Dini to the DCEU like they did filoni for star wars
