1) This actually looks kind of fun.
2) I'm continuously annoyed that Batman is yet again being used as a vehicle to prop up other characters. Who wants to bet that Batman will end up getting sidelined in the movie in favor of development for the other three? I don't mind Shiva, Dragon and Tiger gettin' some love, I just don't want them using Batman to do it.
Lady Shiva's always been more of a grey type than a straight-up villainess though. She helped Batman recover from his injury in Knightfall for example.
