If Warner Bros. brings back Robin to the Silver Screen, he should be Nightwing, and secondly, he should be fighting Batman. They should both view each other as unnecessary. Nightwing should view Batman as just another vigilante menace, and Batman should view Nightwing as an up-start rookie who's getting his panties into a bunch. That conflict, along w/ a villain running free to do as he pleased, because of the vigilante differences, would make a compelling story. The darker the better. Gritty realistic performances are the best!
