I've been somewhat disappointed with the handling of Dick as Batman, with the exception of Batman & Robin. They're not exploring the difference between him and Bruce to my satisfaction (this is mostly apparent in Daniel's run), and the truth is it smells like filler, and we all know that's exactly what it is. DC screwed up royally by revealing that Bruce isn't actually dead in the last page of Final Crisis. We knew immediately after he "died" that he was coming back soon, and accordingly we've just been killing time since then.
The stupidity of that move is completely maddening, as is the brevity of Bruce's absence. We've barely been introduced to Dick Grayson's Batman, and it's already time for "The Return of Bruce Wayne." DC should have taken some notes from Captain America; when Steve Rogers died, the fans believed he had really bought the farm, and more importantly, they believed that his return might not be imminent. They still brought him back too soon (however, his role in Siege gave them a legitimate reason, so it works out for the best), but Bucky's ascension to the role of Captain America had more weight because we felt that it mattered. Dick becoming Batman hasn't mattered, because we've known from day one that Bruce's return is right around the corner.
The only way I can see to rectify this situation is to emulate current events in Captain America (spoilers!), where Steve's return isn't his return to role of Captain America (He's going to direct SHIELD, I guarantee it). That way they have their cake and eat it too: they can keep Bucky going as Cap for as long as it works, and always have the option to bring Steve back in, perhaps years down the line.
