Start with the first series. They are filled to the brim with Lee Mack's signature humour, there is also Miranda, and Tim Vine and later on the Daisy character. It is simply consistent. Good bread at the table of entertainment. Not too heavy, not superficial, because it manages to stay witty and clever most of the time. Then Tim leaves. The show goes a bit low, a bit more, but, hey, it is Lee Mack that carries it and so he does further. Enter new characters. Later on, the series makes a huge jump, in terms of premise and it feels somehow stuck for quite a few seasons. But hey, since it did not gave up, and because it became our friend, we can keep watching. Then it hits here and there a few better episodes. Too much bickering... a much waited Christmas special... a clever plot... a few stale episodes. Overall it is great that is goes on. Good news, the most recent series seems to have hit the jackpot with fresh jokes and fresh situational comedy. This sets up good expectations for the next one (series 12).
