The Shade is an old Golden Age bad guy that used to fight the Jay Garrick Flash. He was a typical bad guy, had dark powers and got tossed in Jail often.
When Robinson created the Starman series he built a deep history for the book that went from the golden age to the present, and one character he picked up and polished was the Shade.
He added depth to the character, and explained his motivations. He was not a villain, but instead a man who had his own code of ethics and honor that he followed, and he super villain days were mostly a result of boredom and such. He was interesting.
The Shade series has focused down on him and revealed bits of his history, background and so forth as the shade tries to resolve a family problem that has come to his attention, and as he is an immortal now it's a pretty big problem. We recently ended a 3 issue arc that focused on his adopted daughter (who happens to be the vampire protector of Barcilona Spain) It's been a good read in my opinion, but then I like the golden age feel of Robinson's take here, and the deep tapestry of ideas he builds to back the character. It's not normal super hero stuff, and a book that is to taste. I'd say read the first one or two and see if you like it. It's hard to say if a reader will or not without a lot of knowing what else they tend to enjoy.
I like it.
