I put it on half way through, and plan to watch it again from the beginning, as I loved the dialogue (I'm not sure what the plot is, but I will catch up with that on iPlayer). I turned it off before the end, as I'd like to see it throughout without it being spoilt by knowing what's going to happen.
It's odd, as the language and manners are very modern, although the action is set in 1760ish, but that's obviously deliberate, to make the characters relatable, and it gives a certain comedy value. It's very Shane Meadows, which is always fine by me. There is a good cast, too.
