Oz is the name on the street for the Oswald State Penitentiary. Our wheelchair-bound narrator Augustus Hill (Harold Perrineau Jr.) takes us through the wacky world of Emerald City, the experimental unit started by Tim McManus (Terry Kinney). There's shankin' and lovin' and cussin' and fightin' but in the end, HBO makes a damn fine prison drama. I tried to get through this whole intro without calling the show 'gritty' but I just can't. It's gritty. And there you have it.
