This is one of the better British TV thrillers to emerge in a few good years. What initially attracted me was another varied acting choice by Matthew MacFayden, but on watching I found myself compelled. It does suffer from some unrealism, but the characters are so interesting, the plots so varied, it makes up for it. And yes, yes, it does rip off from 24, but it hasn't tried to hide it, so in my opinion that's a good thing, seeing as 24 used some of the most innovative effects. Also, some of the secondary casting, such as Hugh Laurie's nasty Jools and Peter Firth's big boss Harry. Also, guest appearances by Anthony Head and Tim Piggot-Smith just add to the strength of this show. I eagerly await the second series, after the excellent end of the first. If you are interested in MacFayden's performance (he is one of the strongest new English talents) then check out the worthy The Way We Live Now (where he plays a cad) and the absolutely wonderful Perfect Strangers.
