It's nice to find a series that deals with a new subject and in a different way, and this one will probably get you barracking for the Russian spies that are in USA back in the 1980's because it's largely from their perspective, following the undercover couple and their unsuspecting kids (nice twist!). It keeps you thinking and there's plenty of action too. I loved it, and Series 2 was just as good when I saw it on Foxtel. This blu-ray is a bargain!
