There seems to be a notion that the Flash flick for the film universe may be a little too similar to that of the TV Universe which much to the chagrin of those who thought the TV show shouldnt have been part of the Man Of Steel and BvS universe and the studio who have lost 2 directors now, have now decided to mulligan the whole thing.
However, is running away from the show the answer?
I say NO. It's not. Face the question of whether these worlds can crossover. The TV show has made it clear that you can move from Universe to Universe. Make the movie a part of that. Have more than one Flash in the film but make Ezra's version the focus of this film. Bring a compelling Flash villain like say, THE PSYCHO PIRATE, and/or Abracadabra, someone who can bend time and space and have him find Barry and Jay and Wally of the Flarrowverse (oh also make sure you give Ezra a ginger white Wally FFS too) and have them come together and save the multiverse and have the ramifications and consequences push both universes forward IE for Ezra's be it The New Gods and for Grants introduce him to The Monitor(s?).
It could work. A good writer can make it work. We don't need another Flash origin. In fact make Ezra's story begin after he has first taken down Eobard of his Earth. His father is out of prison. Let them have a longer relationship than that of the show. Boom.
I am going to write a spec on this I like it so much. Later kids.
