This is just poor planning. They're finally getting some traction on connected movies, but decide that their next endeavors will be disconnected? Why? It's so easy to just throw a little connecting point in these movies to make them all build into one larger story. This is one of the things people love about the Marvel movies. The Hulk movie wasn't very good, but having Stark show up in a tiny scene made it so much better. So much wasted opportunity here. They could have tied the movies to the TV shows and easily brought in a Flash, Black Canary, Green Arrow that people were familiar with. If for no other reason than getting movie goers to go check out the TV stuff. It's like each of these projects is run as a competitor to other DC projects, so they can't possibly work to help each other out. If they're going after stand alone movies, then give us something new like Teen Titans.
Whoever's making these decisions does not have a clue about what their fans actually want.
