I thought the first episode was quite poor.
However, it improved and from week 3 I was very happy with it. Although, I watched them in a block over four nights, having taped them with Sky plus. The acting is consistently good and the scripts have little gems all the way through - e.g. Rosie's holy potato and the vicars blessing of the stones.
There is a refreshing lack of typical sitcom situations and characters. Whilst to some it may be quaint, there is a subtle edge to the whole thing which gives moments of sadness and joy.
I know this is at odds with prior posts, but, having sat through the whole series I feel that it does not deserve to suffer for the couple of episodes that it took to establish the characters and the situation.
So to sum up, it is well worth watching in my opinion and I am really looking forward to the second series.
