With Arrow being canceled and Gotham on it's way out the door, What new show should the CW or DCU do?

Batman Beyond.

CW’s “Arrow” biggest flaw is that it is doing its best not to be a cheap version of Batman, and has totally failed.

I believe that CW’s “Batwoman” will suffer the same fate, and I will not be surprised if it suffers the same fate.

Rather than do this to yet another character, give the CW it’s Batman. Just not Bruce Wayne.

The Justice Society!
Set it in the forties and call it The Golden Age. Have a small main cast and do rotating guest and recurring characters to showcase the heroes in the 1940s. Base the plots off of golden age storylines, updated for modern audiences.
For villains, Solomon Grundy could be a cool season or half season horror mystery/ villain.
I’d love live action, but animated could be good too. I dont care much about ratings as long as the overall tone of the show is hopeful…I’m tired of comics being depressing!
