Since apparently no one wants to do it, I might as well recommend
Powers. It tells the story of homicide detective Christian Walker and his partner Deena Pilgrim, who solve cases involving superheros. The art is VERY cool, reminiscent of the DC animated universe. The writing... Well, the best I can say is that the storyline Forever (which tells the history of powers, going all the way back to the dawn of man) is Bendis' Watchmen. The rest of it is great as well, of course, but if I had to indicate a particular storyline, that'd be the one, hands down. (on a side note, it would make for one HELL of a tv show)
