Slack-paced, undynamic direction, with a one-note, unlikeable performance from star Keri Russell, a phone-in performance from a bewilderingly Americanised Rufus Sewell (couldn't we have had an American actor in the role as her husband?), the usual portrayal of Brits as either stuffy, old-fashioned, or blokishly matey (the always dependable Rory Kinnear as PM - he's OK)... working an impenetrable plot about which it's hard to care. And the occasional four-letter words feel just peppered in because that's what TV drama seems to want to do now, rather than feeling organically part of real dialogue. They just feel clunky! A component of the very clunky dialogue. And after rewatching "The West Wing" right through again till last week, this is so weak, stodgy, and uncompulsive by comparison. Frankly, for me, a waste of time! And I cannot understand why so many people here love it. As TV drama, it's really pretty dreadful!!
