The Mutants was inspired, at least in part, by the conditions in South Africa under apartheid. The serial definitely puts across an anti-colonial, anti-racist message. Which is a little ironic given that there were definitely people involved in the production who thought that colonialism was just fine and that things were so much better when the British Empire was running the world. Having said all that, you might be under the impression that The Mutants is a dry, serious slog. Far from it. While it's not as good as the other stories from this season, it has its charms. The titular mutants are well designed and the contrasting locations (an orbital space station and a primitive planet) keep things interesting.
