I watched Flash, because somehow I thought it was already the DCEU Reboot. It was shit. Ezra Miller is so annoying in it (and, hearing the stories, everywhere esse in life...). The batman scenes were the only fun parts in that movie.
In the original comic, the Flash meets Dr. Thomas Wayne. Bruce was killed in the alley, and the father becomes Batman. He builds a casino to get access to the underworld and uses Hourman's super soldier formula in place of actually training. I was hoping for that story, not just "exactly the same person, but looks completely different."
