"The Ice Warriors", by Brian Hayles, is yet another season five "base under siege" style Doctor Who story, this time introducing the Martian race known coloquially as the Ice Warriors. In this early outing they are purely somewhat conniving monsters, with the "honourable" aspects of their civilisation not manifesting themselves until the 1970s with "The Curse of Peladon" and subsequent stories. Unlike many of the partially surviving "missing" stories, I have not seen the four surviving episodes of this six-parter, and my review is based on the audio release only.
"The Ice Warriors" really is very formulaic season five fare. However, having said that, back in the 1960s it was very much a winning formula, and some of that success is still perceptible now, even if, like many Troughtons, The Ice Warriors is somewhat over-long.
Indeed, after a fairly leaden first episode, things pick up pace quite nicely as we alternate between three sets of characters: The Doctor, his companions and the staff of the base; the renegade scientist Penley (Peter Sallis, who would go on to voice Wallace in Aardman's Wallace and Gromit films) and his fellow anarchist Storr; and, of course, the Ice Warriors themselves. The different groups of characters have their own agendas, but portrayed as the most useless are the ineffectual base staff, who are to break away from the guidance of their computer. Indeed, the unquestioning loyalty to the computer is the most dated aspect of this story, along with the science (apparently, deforestation led to a shortage of carbon dioxide in the atmosphere and caused a new Ice Age - where'd that come from?). Computer dependency is something that sci-fi writers still write about today, but unswerving loyalty to a computer among a group of educated humans is scarcely likely in this day and age.
If one can gloss over these questionable plot devices, "The Ice Warriors" is a decent adventure story that introduces a well-known race of Doctor Who monsters definitely "warms up" as it unravels. Victoria, however, continues to be possibly the feeblest female companion in the series' history.
