I really loved this show! I watched it on TV and have since picked up the DVD and re-watched it twice. It was a very nice, funny drama with a pretty great cast and an interesting idea. It is fairly typical of british tv writing but i do not think that is any bad thing at all.
The show remains largely light hearted throughout but is not afraid to tackle some emotional lows. Getting into specifics would really constitute spoilers but I think Michelle Ryan turns in a very good performance in a refreshingly differnt role for her - less powerful, indepent & BIONIC and more oddball.
The supporting cast also bring life to their characters but in all fairness, the show doesn't really give them too much opportunity to grow. I didn't find this a problem as really it almost seemed to be half the point of the script.
Anyway, typical british comedy/drama in a very good way with a nice subtle undertone that leaves you feeling satisfied.
