Suits got involved too much, part of the JLA isssue was they wanted it under 2 hours and before the year ended because they were trying to get bonuses and show profit because they were about to sell the studio.
They don't know how to handle Superman, Cavil could be great, but they're trying to make him moody and real, when he's suppose t be the boy scout and inspirational. Snyder had a big hand in WW but then they allowed Jenkins to do what she wanted with WW84, and that was bad. Aquaman does well mostly cause Moma is half naked the whole time, hey, sex sells.
Casting issuse with Ray Fisher calling Geoff Johns racist even though his ex wife called BS on it and who is also black, Amber Heard who can't act and is a trash Human being, and now Millar who might actually be worse than Heard.
They tried to fast track and do what Marvel did in half the time.
The new Guy in charge has stated they only want to put out movie they can be proud of, and wanted to build the DCU around Superman. Which is what it should have been. Rumor is James Gunn may be heading the DCU. He did the new Suicide Squad which was pretty good, and at least got the concept. He also killed it with Guardians of the Galaxy, the second one wasn't as good, first half wasn't good, but really ended on a high note, but some of the issues could be Marvel Suit related.
If that happens I bet we see Nathon Fillion as Hale Jordan GL, old and grumpy, but trains John Stewart to take over for him.
I think they are going to start over, but the Flash movie was suppose to help reboot everything, but Miller kinda is effing that up. They are holding on because its testing really well, but it might have to go straight to HBO.
