) please please please don't bring any dick and barbaras in here! i mean, i like their characters okay in the comics, but i don't know that i could watch a repeat performance of schumacher's debacle(s). i need at least one more batman-working-solo flick under nolan's direction with the same cast before i could even think about bringing in robins, batgirls, or even nightwings. [sorry emily!]
I do like the character of Dick Grayson. I've read some of the Nightwing comics, and I like how he's changed. Unfortunately, it seems that the movie franchise (at least so far) hasn't been able to bring him in without the campiness. If they could manage to do it, I think it'd be interesting.
Or, heck, why not just make a separate Nightwing movie?
