Series like tihs are schools for dramatists and screen writers. How to use a short time and pack everything essential to the story in it and still don't overwhelm of frustrate your audience. I find it amazing that no one so far has written here about this series. It is a very good example how to create a compelling stroy in just 30 minutes. Nowadays we are used to films running far over 90 minutes, the watershed of films telling a regular story. That people have been able to tell the same story in only 30 minutes sounds impossilbe. well, watch this and learn! By the way, Nigel Patrick is probably the most underrated british film and TV star of the 50ies and 60ies and it is high time that he gets rediscovered. And another bonus is William Smith in an early role as as a straight guy and partner to Nigel Patrick.
