I remember watching this as a child during the 1970;s and it scared the livings daylights out of me!
It was very ahead of its time when it was made and was completely different to anything else around at that time. I can remember the lead actress walking down the street and everyone has gone crazy and they were bashing their cars, and then wandering around like nomads. can't remember the middle episodes much, just the lead character trying to find her parents I think. I vaguely remember her meeting up with other people. I remember the end episode where everything appears to go back to normal again, and the girl, Nicky I think her name was, emerging from some sort of cave or hiding place and there was a shot of a train running over head which indicated everything had returned to normal. It didn't really explain why everyone rebelled against all things electric etc and why it turned everyone crazy. It would be great if the series could be repeated again, and to see if it still held the power to scare children today. Its a pity that another series was not made at the time as I feel there was scope for another series, to see if the madness returned. What a great children's TV classic!
