DC needs to take a step back, realize they aren't catching up to Marvel any time soon, if ever, and just think through the stories they want to tell. It doesn't need to be in detail, just the overall arch they want to build in their universe. They also need to stop chasing that Nolan darkness. They seem to be going in blind to everything and just making stuff up as they go. It took Marvel what, 4 years to get build to The Avengers? In those 4 years we saw each main hero get a fleshed out story and background. Justice League comes out this year and I don't know the first thing about Aquaman, Flash, or Cyborg. Hell, I don't even know that their DCMU Superman is all about.
Just breathe DC, and take your time.
