I also found this on YouTube -- I had not heard of it before.
It is quite compelling watching -- sinister and chilling without any melodramatics to it. It is done, as many British dramas of the time were, without incidental music, which adds verisimilitude to the drama -- I particularly remember this from The Sandbaggers, one of the best spy series I ever watched.
The leading actors are all very good, from a young Anthony Valentine to the mature Michael Aldridge.
I began to see where it was leading before it got there, but that did not diminish the eeriness of the society that was being painted. Made in 1973, this series forecasts much of what has happened since as people have accepted the reduction of their freedoms in the name of security.
A salutary tale, well worth watching for its dramatic story and for its prescience. Recommended.
