This serial is a thrilling story, with a great twist concerning the Mashmen being the ancestors of the crashed ship's occupants. Romana doesn't get much to do, and it is a shame that in his debut story Adric spends a short amount of time with the Doctor, but Andrew Smith does a brilliant job at evoking an unnerving vibe with Alzarius. The image of the Marshmen stepping out of the Mistfall fog, in particular, really stands out.
