Hi,
Dunno if it's a help - but you could always go to
www.uknova.com and download the episode, I did and watched it last night.
It was fresh, new and I enjoyed it. My wife hates sci-fi and she enjoyed it.
There are lots of quirks like they didn't call WPC's until mid 70's etc., but hey its a drama!
Someone suggested a bit of cross of Quantum Leap meets The Sweeney ... but definatly something I haven't seen before
