DC needs to break free from Warner Bros

Definitely. WB has no idea how to handle these stories properly outside of the occasional good solo outing.

The DC movie (and television) side needs more autonomy just as Marvel Studios is separate from Marvel Comics, though both are under Disney. They need someone like Feige who both knows his/her comic stuff and can throw his/her weight around with the other execs.

Everything else can stay as it is. Like DC animation would suffer without WB resources. Remember who made Bugs Bunny.

Who should own DC if they go their separate ways? Disney?

It’s not going to happen. Overall, DC has still been profitable. It’s the people who are running the show that needs to break free.

DC probably benefits a lot from being a Warner company, the bigger brand probably opens more doors for them far easier than if they were on their own, plus the movies would be less of a risk, WB is going to be making X amount of movies a year regardless why not make 1 or 2 of them from their super popular comic IP's? if they bomb it's less impactful to WB than it would be DC, as we see with Disney all the time, because Disney has Lucasfilm, Marvel Studios & Pixar making them shitloads of money if they release a Mary Poppins Returns and it doesn't do huge numbers oh well because Marvel brought in $4b at the box office alone last year and like $3.5b alone this year, but a Justice League level flop could kill a smaller studio like DC would be without WB behind them, or DC would just be doing a 90's/00's Marvel and licensing their IP's out all over the place with little control themselves.

DC should be given more autonomy though imo, like Marvel has, sure they still operate under the Mouse's rule but they can decide how they follow those rules and make things their own, Marvel had a bumpy start to the MCU outside of Iron Man, but they held true and The Avengers made them a fortune, the DCEU also started off bumpy and WB immediately stuck their paws in trying to "fix" things where if they had left them alone I don't think it's hard to believe that the DCEU even if not critically a hit would have come out of JL in far better shape, then they could adjust their plans going forward once their "phase 1" was completed.

Yeah but considering the characters that they have the rights to plus the history of previous cbms they already made, the fact that DC has only accomplished this much (and still struggles) is proof that they're not doing as well under WB as they should be. And yes, they need to choose better directors and writers, but who does the choosing anyway?  Pretty sure WB had a lot to do with those decisions.

Who were the the ones who rashly made the decision to hire Snyder and grant him free reign to the whole DCEU? Who were the ones who kept messing around with Suicide Squad till it became a disjointed mess? Who were the ones who wanted to rush crossover movies instead of building up to them properly?  Who decided to hire Whedon to replace Snyder when it's fairly obvious that their directing styles are vastly different? Who decided to have a Birds of Prey movie before having a Flash or Green Lantern movie? Who decided to promote Black Adam and Deathstroke heavily and then just never do anything with them anyway?

So no, WB is not blameless in this regard. 

So they say. And if they do then great, but I'll believe it when the movie finally moves to production. Because it's not like DC/WB hasn't announced directors before only to eventually cancel out on them. 

They should but they can't.
