afteryou mentioned the Walking Dead - I liked the first season of that, but season 2 has been a bit ho-hum. I've started reading the graphic novels, which are excellent so far. The storyline diverges quite quickly, but that's ok. It's only 3 episodes, but I highly recommend a BBC mini-series called "Black Mirror". Three unrelated stories about the not-so-distant future. Very thought-provoking.
I really enjoyed season two of the Walking Dead. Yeah, It got a little slow in the middle, but you at least have to see the final episode, where they introduce the prison, and Michonne. Season 3 is gonna be great. I'll tell ya, if I could live in that world just for a bit, that would be amazing!
"An Endemol press release describes the series as "a hybrid of The Twilight Zone and Tales of the Unexpected which taps into our contemporary unease about our modern world", with the stories having a "techno-paranoia" feel.[2] Channel 4 describes the first episode as "a twisted parable for the Twitter age"."
