Without getting into spoiler-type review writing, I am going to keep this simple. Nightwing is an excellent comic. Great characterization, great art, and great storytelling. Written by Kyle Higgins, and drawn by Eddy Barrows and Andres Guinaldo, they are taking Nightwing into some interesting territory. The first arc spans 7 issues, and deals with Dick Grayson inheriting Haly's Circus. He explores his history, and gets to experience a little betrayal thrown in for good measure.
Barbara Gordon, back as Batgirl, makes an appearance in the story, and the dynamic between her and Dick is always fun to read. If any two characters in comics should be a "couple", it's these two.
Issues 8 and 9 deal with the big Bat-crossover "Night of the Owls". Thankfully, the stories were self-contained to Nightwing, as opposed to buying 73 other Bat-titles to know what in the hell was going on. Night of the Owls is another look into the Grayson family, and Dick gets to meet a long lost relative.
Excellent stuff, to be sure. My only complaint, and it's a small one, is the costume. Replacing the lighter blue accent is a red one, and while it doesn't look bad, the blue was better, in my opinion. Again, who really cares? The art and story is excellent.
