THIS. I have been dying to see a live action portrayal of Nightwing for so long, and the only way to do it well would be a show. It would be so much more interesting that a ****in' show about RAVEN. Wtf?
It's just something that popped into my head. I always liked Dick Grayson growing up. My dad was a kid when the original Batman series was on TV, so I grew up watching the Adam West-Burt Ward reruns, watching Super Friends and reading Batman comics. But I didn't really get into the Nightwing character until I got back into comics around the Final Crisis/Batman RIP time period, and I bought lots of back issues of Nightwing to become more familiar with the character on the assumption that he would become the new Batman. So I read lots of his backstory, and of course followed the character through Battle for the Cowl, Batman & Robin, and into the present issues.
Dick Grayson is a bada$%, plain and simple. So you set a series during the beginning of his time as a police officer in Bludhaven. It's basically a crime drama/detective show. Show him working the beat with his cop buddies, and at night he does double duty as Nightwing. The costume wouldn't be too crazy (it's just black & blue spandex and a couple batons), you could hide him a lot in the nighttime shadows, there wouldn't be tons of special effects to worry about, and with all of Dick Grayson's contacts within the Batverse and as leader of the Titans & Teen Titans you have a huge list of superhero & supervillain guest starts.
Heck, if the series progresses a long way, you could even take it as far as including his time as a museum curator. That would certainly lend itself to locales outside of Bludhaven, as Dick Grayson could travel the world looking for artifacts and such. Once you expand the scope of the series to worldwide, and not just focusing on one city, you've got that many more heroes and villains that can pop up.
I'd love to see Barbara show up every once in a while, Tim, maybe he even hangs out with Alfred a little when Bruce is out of town on "business." Now that Conner's been introduced on Smallville, have him show up to lend a hand when the heavy hitters come to town (and keep Lucas Grabeel as Conner...I liked him in 'Scion'). And if you need love interests (as a CW-type show always does), well, Dick's had a few of those.
All right, now that I'm actually thinking it out, I really want it to happen.
