This series is awful, the main character is called Dr Jackman not Jekyll so they didn't even get that right. When the "transformation" occurs it's so cheap and nasty I'm surprised anyone really notices, what's up did the BBC use up all the FX budget on Dr Who? James Nesbitt simply brushes his hair back, pulls funny faces and overacts. And we are supposed to believe that his own wife and kids no longer recognise him, it's ridiculous.
Then we have the hammy "American" secret agent/whatever who can't do an American accent and the ever so professional assisitant who falls in love with Dr Jackman after a week.
This is so bad it's like a car crash, you don't know why but you can't turn away from it no matter how much you want to.
Save your money and buy something else instead.
