A very predictable storyline in terms of trajectory and ending but my wife and I both enjoyed it (especially my wife) and made for good viewing on a very rainy gloomy day (which we've had an awful lot of for so many weeks now)
The lead characters were very likeable: the hero throughout and the heroine more and more as the series progressed. Some of the villains were very good too, especially Leon's girlfriend, who put in a deft performance. On the other hand, the heroine's ex-boyfriend was a bit hammy at times and close to over-acting although I get that they wanted to portray him as psychotic. His 'entrance' at the awards ceremony was hilarious.
As for locations - I think I spotted Exmouth Market - there weren't enough street scenes. A lot went on in small rooms and so the filming felt claustrophobic at times. I'd also criticise the music, which was pretty awful, cheesy, generally sub-par.
The subplot about Mr Prior and his lost love got a bit twee and very predictable. Surely the writer could have done a little better on that front?
