I think they shouldn't bother with Rachel Dawes and instead introduce Selina - but don't make her a villain, just make Catwoman the love interest of the story. She doesn't need to be treated like a huge villain as in Batman Returns cause she's not some evil hell-bent on destruction type of antagonist. She'd serve her purpose 100% if she was more on the so-called political side of things with Bruce and Batman. It'd be cool if the first scene had Scarecrow being captured by Batman, but that probably won't happen. Penguin shouldn't be an immense character either. I think The Joker shouldn't be copping out to anybody.
