Unique and utterly original. Fantastic writing and acting. So different from the usual banal tv fare, and tragically under-rated. I've watched it over and over again, and there's always something new, missed beforehand because it's so well written and the acting is first rate. It's such a shame that the show wasn't given more recognition, perhaps because of the sex, violence and language, while other, much blander and less thought provoking television was lauded. Without the groundbreaking Oz, I doubt they would ever have made the decision to risk investing in the more popular The Sopranos. I hope it gets rediscovered and fully appreciated at some point in the future.
