This adventure caused me no small amount of confusion when my dad first bought the video. At that stage in my young life, the only Tom Baker adventure I had seen was the 1993 repeat of Genesis of the Daleks. So when I saw the good Doctor and Sarah Jane on my parents’ TV screen, I mistakenly concluded that this was the same adventure I had seen before – an impression that did not take long to be corrected!
Planet of Evil is an exceedingly clever story, which does not really feature a monster in the traditional sense. It is definitely of the same ilk as historic base-under-seige stories, as first a planetary expedition, and then the rescue ship come under the attack of an unknown and malevolent force. When the Doctor and Sarah respond to a distress signal on Zeta Minor, they are initially blamed for the death of the expedition by the lone survivor, Professor Sorenson. As the story plays out, it is revealed that Zeta Minor is on the very edge of two universes – the universe of matter, and the universe of anti-matter. As Sorenson becomes infected by the anti-matter, the Doctor has to find a way to return all of the anti-matter specimens to Zeta Minor before the rescue team are pulled into the anti-matter universe.
While I admit this largely went over my head as a child, I adored the plot when I was old enough to appreciate it! As with many Doctor Who adventures that I best love, it combines a straightforward plot with clever twists, great characters, and of course the indomitable presence of the Doctor! Season 13 is quite rightly held in very high regard by fans, with the on-screen chemistry between Baker and Sladen exceptional, paired with exceedingly strong stories. Planet of Evil is a fine example of this at work.
