The people running the TV DC Universe should be running the movie version as well. I have ZERO interest in Green Arrow or Ollie Queen in any shape or form. But so many other DC characters that I do have interest in are appearing in that show that I feel I must check it out.

Likewise I know they hired some other actor to be the Flash for the movie universe but at this point just make Grant Gustin the Flash in the movies (and Melissa Benoist, Supergirl in the Superman films alongside Cavill). Not only would it give the shows themselves more hype but it would remove the need to give origin stories or explain who these characters are. The TV shows could be an extension of the movie universe and vice-versa (especially if you keep the movies the only place where you can see Batman, Superman and WW).
