Re: How many years should WB wait before making a Batman reboot?
I think the wait between Batman films builds up anticipation and makes it more special. And I agree, WB has a chance now to let Superman be their flagship character for the first time in 30 years. Let Batman take 5. I know this is all irrelevant as they are pressing on with Justice League, but I'd have no problem waiting another 5 years or so for the next Batman film.
I think between the Nolan films and the Arkham games, there is a bit of Batman overkill right now. Let it die down a bit and let the public appetite grow naturally. I would do MOS, MOS 2 in 2016, then the rebooted Batman in 2017, and then finally Justice League in 2018. I know that's not how it'll go down though.
