In contrast to the first review, I'd never liked James Nesbitt before: in fact I found him extremely annoying in those twee adverts, but this series, which I only entertained at all because of Steven Moffat, is getting better by the week.
The first week confused me, I confess, because I was expecting a straight modern take on the old Jekyll and Hyde series, and instead I was plunged head first into the hideous world of a man living with his own dark side and using every means at his disposal, from CCTV to hiring a new PA, to deal with that.
But after that intial discord this series has so far delivered so much more than my mistaken belief could have done - and it all starts to come clear in ep 4, aired just before I typed this.
I love the La Femme Nikita(tv series)-esque stylings, and the "Are you my daddy?" question in ep 4 made me howl - echoing Moffat's Hugo Award winning "The Empty Child" & "The Doctor Dances" episodes from season one of the new Dr Who.
But this isn't just one for geeks - if you've ever been alarmed by your own dark side, or woken up after one too many wondering what the heck possessed you the night before, this series will strike a chord. Genius.
