Never watched Oz... sounds like I should be adding it to the list.
I am actually watching Fringe on and off at the moment - if that isn't a reason to find an old show to start on then nothing is.
Sons of Anarchy has some proper dark prison fight / violence shit as well... really nasty stuff.
Whenever it was, (late 90s probably), Channel 4 were broadcasting it,
but long ago enough that I was still routinely using a VHS recorder,
it was, and remains, the only tv show where I immediately rewound the first, introductory episode & watched it again.
If you do watch it, give it a break, seeing as it is 15+ years old,
it was really nfsw in its time,
so a lot of the tv you see now is inhabiting the space Oz carved out,
and,
given the body count, (not really a spoiler for a prison-based show),
you'll be amazed the number of faces you recognise in cameo, and main roles, who served their time in Oz.
