Like the other reviewer, I stumbled across this series by accident when I was looking through the ratings and didn't know what this show was about. Recognizing several actors I enjoy watching, I decided to look it up and found it buried on NBC's website. The synopsis looked interesting and follows similar crime dramas we also enjoy and felt to me like a Criminal Minds Europe type of show.
We watched the first two episodes and thoroughly enjoyed them. It had a Spooks feel (MI-5 to US folks), Criminal Minds and a bit of Law and Order mixed in with a lot of suspense, action and a few twists. It has a great cast and I'm not bothered by its size. It's a very cerebral show that gets you thinking and I do hope it lasts the 10 episodes its scheduled for to see how it plays out. Given the poor quality of shows available for viewing this summer, this is a breath of fresh air.
Shame on NBC though for keeping this jewel hidden... a little bit of marketing and it could be owning its time slot easily.
