The yellow brick road of the Oswald Correctional Facility (affectionately known as "Oz" among the inmates) leads to "Emerald City," an antiseptic cellblock of cement and glass overseen by prison-reform advocate Tim McManus (Terry Kinney). The first episode introduces its two most compelling inmates: meek lawyer Beecher (Lee Terguson), who transforms from a vulnerable lamb to a fearless, drug-addicted wildcat, and Muslim activist Kareem Said (Eamonn Walker), a fiercely non-violent leader whose campaign for reform explodes in a season-climaxing riot. The stunning first-season cast also features Ernie Hudson (the warden), Rita Moreno (a worldly drug-counseling nun), and Edie Falco (who jumped from her role as a single-mother prison guard to mob wife in The Sopranos). It carries no rating, but the drug use, nudity, and brutal violence make this highly inappropriate for young viewers and unsuited to the squeamish. Oz pulls no punches in its portrayal of prison violence and predatory abuse. --Sean Axmaker
The first season sets a lot of seeds for future happenings, but it is a fine season on it's own. You just never know what will happen. I never saw the first 3 seasons, I watched 4 and 5 and have seen some repeats of the first 3 so watching this DVD set was a huge treat for me. The Show is very easy to follow, has a ton of great acting and is just plan amazing.
I would suggest this to anyone who likes drama's. Yes the language is hard and there is some nudity (mostly male) people need to remember that this is a prison setting and that is what would happen in any prison. Sit back and enjoy. I can't wait for season two to come out in January.
