I really don't see the humour in this series, perhaps it's my loss, perhaps I should have tried to watch for a bit longer. However congrats to the team for their awards.
Series 1 is available on DVD (Peg) from Amazon, suggest you check to see if it's available from your library first.
As for US v Brit humour, I never could understand how Benny Hill got such recognition in the States, oh well.
