I much prefer Joss have a blank canvas to work on, rather than feel tied down to decades of material. This is the best way to go, as far as I'm concerned.
Dear Everyone Experiencing The So-Called "Batman Fatigue",
By 2016, Batman will have appeared in three big-screen films since 2008. By 2016, Iron Man will have appeared in six films in the same amount of time. Find new s*** to diagnose the current state of cinema with.
