You guys get better every week. You know your audience, you've gotten down your timing, and you've definitely grasped control of your own show.
Regarding this show:
Batman has always been his own worse enemy. He's created more super villains than any other supper hero I can think of, and other than locking them up he's never directly destroyed a villain. Batman has never been the cure, but he has always been able to manage the diseases he comes up against.
Nolan's Batman universe has always been more grounded than the others. Some characters really can't come into play in their more colorful (and sometimes alternative) forms. However, any number of super villains would have been great to bring into this Batman universe with some adjustments. The Riddler would have been interesting, but it probably would have come off more as a Die Hard With A Vengeance than a Batman movie. And, the worse thing about the Riddler is he kind of lacks a real motive, and maybe that's the biggest riddle of all.
