I'll be the first to admit that I am not terribly interested in what DC Comics is doing in the movie space, most of which seems to be dictated by less of a love of the characters than creating new revenue streams.
And I don't for a moment assume that there's anyone making movies minus the intent to make a profit, but when I think that it becomes too blatant I tend to lose interest.
For instance, while there are many people that enjoyed Zach Snyder's interpretation of Superman, Man Of Steel, I felt that by making him darker than is traditionally the case the filmmakers ignored the essentially optimistic nature of the character.
Batman is at home in the dark, Superman, not so much, which I think had a direct effect on its box office (now keep in mind it earned over $668 million, which is a lot of money. That being said, I think that if it were more optimistic it would have done even better).
So on top of series' like Gotham, The Flash and Supergirl there will be a new series on TNT called Titans, based on characters like Dick Grayson, as he transitions from Robin to Nightwing.
The trailer above has nothing to do with TNT's upcoming series, though I think it does show how popular the character is (plus, it's a pretty good looking fan-made trailer).
The path that Warners and DC are taking concerns me because they're using characters that have huge potential in the movie space on television. If they were going to, after a point, let the actors transition the characters into feature films, then I could see it (like what Marvel will probably do with the characters being introduced in in the four new series based on Daredevil, Luke Cage, Iron Fist and Jessica Jones that they're working on for Netflix).
But seeing that they don't have any intention of doing so, it seems that Warners are painting themselves into a corner.
