What I hate about American comedy series is the perceived need for a punchline every 15 seconds. What I love about this series, is the gentle, ambling approach the script takes, as it follows its characters through their daily lives. And they are characters - wonderful ones - but never caricatures. Judi Dench and Geoffrey Palmer are just perfect in their portrayals, and they are ably supported by a talented cast. Every now and then there is a good, solid belly laugh to be had, but for the most part the humour is subtle and very clever. I feel very warm towards these characters. If they were real I think I should like to invite them to tea. Dench and Palmer appear to enjoy their roles, and when they exchange glances it seems to be not acting, but genuine regard that they show towards each other. May they live happily ever after...........
