It was a fantastically poorly overdubbed Chinese import with special effects that made 1970’s Dr Who look slick, but it was quite the craze in my school. They put it on the early TV slot so you’d run home from school, jammie dodger, squash, watch Monkey then all out to batter the living daylights out of each other re enacting the fight scenes.
This has now morphed into slo mo fight scenes in the kitchen with my kids where they know that if I shout (in a stereotype Chinese voice) ‘ahhhhh, monkaaaaay’, they need to be on their slo mo fight game.
