The BBC drama "Threads" still scares me 25+ years after I first saw it:

One thing to note about this drama, where over 90% of the UK population are eventually killed, is that it is based on an official exercise called Square Leg that was generally regarded as being rather optimistic, a real attack by the Soviets would probably have been far worse:
