Re: Batman should die in the next film!
You don't need to re-start the franchise over again. BB did the origin story well enough that another should really not be necessary, possibly ever again. We're not talking about reboots(that's what you need to do when you royally F it up) or a re-start(basically another name for a reboot), but rather a reimagining. A different take to be started somewhere with Batman already ensconced as Gotham's dark knight/protector.
My God, did that smell good!
