Excellent eighties UK sci-fi children’s TV series about a disembodied alien intelligence and the consequences of its symbiosis with Matthew, a young English schoolboy as the alien ‘Chocky’ attempts to gift Earth with free energy technology.
Based on a series of books by Day of the Triffids author John Wyndham and though a ‘kids’ TV series, like many other UK science fiction children’s TV series of the 70s/80s like The Changes, The Tripods, Sky, The Tomorrow People and Children of the Stones, it never dumbs down and given the budgetary constraints of the genre, it privileges the imagination over special effects.
Fans of the theme song may like to know that the track is by John Hyde and is taken from the 1982 library music album Red Kite by Astral Sounds and was originally called ‘Coral’.
