YMMV / Doctor Who S6 E4 "The Krotons"

• What Do You Mean, It's Not Political?: An example part whimsical, part serious - this story broadcast in 1968. It's hard not to see a story where the Doctor helps students throw off the rote learning of the "teaching machines" and their exploitation by the Krotons as a bit of an allegory when he does it by showing them how to make acid. Literal acid, but acid nonetheless. In fact, it started Robert Holmes' long tradition of slipping suprisingly radical messages into what was nominally kids' TV.
