Have quite enjoyed seeing the early re-runs of this series, which stand up better than some 70s comedies. Some of the attitudes now seem dated - it would seem strange nowadays for a young couple living together unmarried to be seen as so controversial - and the cheap cracks against Chinese people now jar. As others have said, the later scripts settled down into twee predictability, and it seemed a pity, given that Robin's character was based on the one he played in Man About the House, that no mention was ever made of his former friends, and that the scripts couldn't accommodate at least one guest appearance. Sad that Richard O'Sullivan's later life has become rather a sad one.
