Some great suggestions up to now. I've seen Prison Break and The Shield. Both decent. Sons of Anarchy and Strikeback seem popular so might be worth a go. Also seen The Following. A bit disappointed they are doing a 2nd series as thought it was nicely tied up and already getting a bit far fetched. Will still watch like!
Never really considered The Walking Dead as not really into zombies etc. However, might give it a blast as a lot of people seem to like it. I've not heard of Justified.
Heard a lot of decent things about Lilyhammer and Orange is the New Black. Anyone seen these? Are they any good?
I'm not really into zombies either but really enjoyed Walking dead. Definitely worth a watch.
