Reboots will keep being made. And I advocate that. These stories need to be passed on. I want to see as many different interpretations under the sun. I want them to stay fresh. For Incarnation films, like Superhero Films, or James Bond. Hence the Superman Reboot in production, hence the Spiderman reboot in production.
Maybe it's just me, but It always seemed obvious to me that this is the end of Nolan's Batman. His films are done, his vision is done, even the title is poetic and Talia comes full circle from her father being the villain in Begins. What director would want to continue, conforming to his leftovers, in his world, in his continuity? Nobody suddenly continued telling Burton's take. Nobody continued telling Schumacher's.
