Oh dear. This has dated badly. I recall seeing this when it first aired and enjoying it. The recent passing of Le Carre prompted me to revisit its pleasures. I got to Ep. 3 and gave up. How styles have changed. The acting is stilted, the characters unbelievable, sound poor, production of low standard (or low budget). Of course, many shows of that era have also dated - as have I. However, that is no excuse. It should have been better.
