Doesn't this project have a New Mutants problem tho? Even if it's great, Affleck probably out, Cavill unclear if he'd come back (or more likely unclear if WB would pay what he thinks he's worth), Ezra Miller seems unemployable ... Maybe it will even help that it's an inevitable one-off -- forced world-building was probably the biggest gripe about Ultron -- but I don't know that Synder does anything DC after this.
