I stumbled over this one on a Sunday afternoon during a top-ot-the-hour channel surf. Readjusting my American viewing apparatus to accept a cop drama that was cut at less than 10 edits a minute, this baby snared me hard. I drooled until I was able to catch the rest of the episodes, and I found myself moving through the day hungering to answer the phone, "D.I Creegan..."
This show rocks in that the viewer is REQUIRED TO WORK to figure out the details of the backstory, relationships that existed before, and to hang onto a storyline that is not concerned with over-explaining; you need to keep up with the pace. This story is real and happening, transferring a realistic impression of copwork from the inside, tempered with just enough "X-Files" in their "Elite Special Ops Force (or whatever it's called)" to be convincing not in the fantastic/horrific, but in The REALITY. No passivity in attention here; snooze=loose.
Think the complex, multi-episodicness of "The Prisoner" with the acting/directing savvy of "NYPD Blue" and the cinematic re-par-te of, say, John Sayles if he were to shoot contemporary London. (The EXT. - NIGHT's are a little too blue for me, but hell, I ain't the shooter...)
"Touching" is pretty dang good, guv-nuh, as hard-boiled as you'll get across the Pond.
