Also, one I forgot - Lilyhammer is very good. Has Steven Van Zandt in it (of The Sopranos and Springsteen's E Street Band).
The missing is on bbc now about 4 episodes in on Tuesday's available on i player. It's a bit like the bridge.
I'm loving The Walking Dead at the moment ....I'm half way through season 2 ....but it is only on Virgin box sets till 11-12-14 ......doubt I'll get up to the current series in time Vikings was good too
