I started watching Oz over the weekend. I am about 7 episodes into the first season and am enjoying it. It is funny how many faces I recognize now from that show (Mister Eko!). It must have been a big break for a lot of actors.
What I do find mildly annoying about the show are those breaks with the guy in the wheelchair and the spinning cell. It just comes across as so cheesy to me, especially when he has that awful headset mic on. So bad.
I love O'Reilly though. [spoiler]He is such a bastard and I know that eventually everyone on the cell block will have a reason to kill him, but it is fun as hell to watch him work that ladder one rung at a time. I also had to chuckle at the cannibal guy that started going to mass after the priest explained that the Eucharist actually transformed the wine and bread to the physical body and blood of christ.
