Back in the 70s, kids TV was full of the weird and wonderful. Whether it was on ITV or BBC1/BBC2 (youngsters: we only had three channels back then), you could come home from school, turn on the TV and pretty much be guaranteed some mentalist of a commissioner had ordered up 25 minutes of LSD-fuelled lunacy that seven PhD students couldn't decipher the plot of but which was sure-fire certain to scar you for the rest of your life.
We could go through the list without too much trouble for quite some time and still not be complete: The Tomorrow People, Ace of Wands, King of the Castle, Timeslip, Sky, Catweazle, The Feathered Serpent, Escape into Night, The Jensen Code, Raven, Into the Labyrinth, Michael Bentine's Potty Time, Pipkins, Robert's Robots, The Owl Service.
See what I mean? And I haven't even started, really.
One of the most complicated, clever, "scare the sh*t out the kids", yet hard-to-fathom shows was the seven-part serial Children of the Stones. This followed the adventures of astrophysicist Adam Brake (Gareth Thomas of Blakes 7) and his son Matthew after they arrive in the small village of Milbury, which is built in the middle of a megalithic stone circle. There they meet village squire and noted astronomer Hendrick (Iain Cuthbertson) and possibly the most well behaved bunch of kids in the world, almost all of whom are doing quite well in quantum mechanics at the village school.
As you do.
Yes, there is something rotten in the heart of this village Eden, and it's not just the quantum mechanics. There are mysterious deaths, Matthew seems to have a psychic link with a mysterious painting, there's the mysterious stone circle that somehow seems to prevent them leaving the village, there's the mysterious housekeeper, there's the mysterious personality changes of anyone who goes to dinner with Hendrick. You get the idea. It's all very mysterious.
Cue the mysterious, weird and soul-chilling title sequence, followed by the first ten minutes of the first episode.
