I tried watching Oz the other night since the first time I saw it six years ago (which I mostly blocked out of my memory) and I couldn't get through the first fifteen minutes. It was awful, pure trash. The "gritty" music video, blatant sexploitation of Ashanti, and David Allan Grier mentioning that the Muppets are, "The most powerful puppets in the country!" Then finally the Muppets show up and the writing impossibly nosedives even further south.
For now, I'm only relying on my vague, discarded memories. Piggy is a biker chick, Gonzo has a nipple ring and of course Ashanti ends up showing even more skin so she can be famous!
Point is that I'm glad the Muppets are getting the better treatment that they deserve, but after Oz... can you really blame some people for being ambivalent?
