True Sith, but does any casual audience goer have any idea of the significance of Ras al'Ghul? If he wasn't on the West Batman tv show, then no one out there knows him.
Right. However, I believe people weren't focusing on the villain so much as how Bale does as Bruce/Batman. Also, from various people online and off, I got the same question asked to me... "Why didn't they choose a villain like the Joker for the first movie?"
