Foolishly I left the UK to live abroad round about the time this was aired on TV, and so have come to it later than most, via DVD.
If I said it was perfect, you would say I was exaggerating, but I would not be. Not only does it capture the era, the mood and the battles therein exquisitely, but the characters are drawn and portrayed with straightforward subtlety and affection. There are no horrible surprises, but it is a gentle very funny mystery which is sorted out tidily. I look forward to the next two stories - also contained in the boxed set - to watch them again too. I'm lucky in that I remember very few things thoroughly, no, it's not dementia, I've always been this way.
The poor reviewer who didn't get it - I hope he's not still in therapy.
