At this point, I think DC just needs to quit trying the live action thing for awhile. They hit it pretty good with the Nolan Batman films, Arrow, The Flash and Wonder Woman, but since then its anywhere between meh (BvS, JL) to dumpster fire (Titans, Suicide Squad). Even Disney decided to back off on Star Wars a bit after one movie that fractured the fanbase and another that barely moved the needle (not that it was bad, just poor release planning).
