Did you see my Oz post in my LJ, Hec?
I did. I loved Oz quite a bit in S2, but even by S3 it was straining my credulity. Not that there was any drop in the acting or writing, but just after the umpteenth gory revenge scenario with the same core group (with new fish), it was hard to believe Em-City would've been kept open. Everything was always at such an intense pitch it was hard to believe it would stay at that level.
