Yes, I enjoy it very much indeed. But then, I like ALL the current US cop shows and watch the lot! I loved 'The Shield', with its knife-edge storyline about the bent cops working their own little deals. I love CSI:Miami, even if everyone looks too, too well-groomed for such a humid climate. Yes, love the lot of them!
I find our own offerings a strange crew: Midsomer Murders is full of completely wooden acting, and every bit as twee as a Miss Marple, but I still enjoy it (and for a tiny village, it must be the world's Murder Capital with the ratio bumped off weekly). I'm finding Ray Winstone a bit tiresome with his bawling and shouting about bugger all in 'Vincent', and the pointless intrusions of his dopey ex-wife. Perhaps a spot in 'Eastenders' would suit, where they all bawl and shout all the time. 'Jericho' has done a terrific green-screen job at replicating a small, seedy part of 1950s London, but I'm waiting for more than just one character to develop.
That's what I like about the US stuff - you get your main character, but all of the others carry their weight in their parts, they're not just add-ons to act as the goofball or the straight man or some muddled, peripheral lurve interest. NYPD Blues was probably one of the best ever shows - everyone got a full-on personality to develop, with good back stories as well as running themes that took you from show to show and series to series.
