State of Play - other recs?

Two friends of mine just saw State of Play, and are desperate for other quality British shows on par with that--especially thriller action-type shows.

I have Spooks recommended. They've already seen Life on Mars and adored it. They've seen Hustle and adored that one as well.

Anyone have some recs for me?

OMG WTF ETA: The UK show Spooks is called MI-5 in the U.S. Season One DVDs at amazon.com say 360 minutes. Season 1 DVDs at the UK amazon asy 460 minutes. I'm assuming, therefore, that the DVDs in America are of the BBCA version, where they cut all the swearing and nudity. WTF?? Is this some sort of typo, or is America so sad that they can't even release the complete show on DVD?
