I've read a fair amount of Batman, but it's always been more of the dark knight and less of the Batman and Robin stuff. I'm fairly new to the mythos and all, but I've been catching up recently, especially after watching the absolutely fantastic Under the Red Hood.
I really like the character of Dick Grayson. He bring a completely different atmosphere to the caped crusader. Dick is funny and easygoing as opposed to Bruce's general brood and gloom. It's great that he's finally getting some time in the forefront.
The relationship between him and Damien (the current Robin) is incredibly tense. Damien is Bruce's son, raised by the daughter of Rhas al Gul. Essentially, he is a tiny little stoic badass. He speaks without contractions, uses the term "unwashed masses", and does a lot of flips. Damien and Dick really help flush out the character of Bruce, and it's important because right now the idea of Bruce is really the focus of the Batman series.
I'm hoping to read more about Dick (haha) in the next few months, especially what will happen when Bruce returns. Anyway, Dick Grayson is awesome.
