Review by Jacob Licklider

Six-part Doctor Who serials are often particular favourites of mine, simply because in storytelling there is quite a lot you can do in six episodes.  The 1970s revolutionised the six-parter by essentially dividing them into a four part story and a two part story which I have discussed at length on the Internet before because it allows for more exploration of characters and a plot that needs to be able to go through the length with at least one big twist at a point in the story to send things off in a different direction.  Big Finish Productions have done six-part stories before, ‘The Next Life‘ and ‘The Game‘ were the earliest, and several of the Lost Stories range were allotted six episodes as that is how those scripts were pitched and often written which worked especially well for stories like ‘Farewell, Great Macedon‘ and ‘Lords of the Red Planet‘.  This year they’ve dipped their toes into a single seven part story with The Annihilators which I enjoyed and reviewed, but as the rest of the Doctors got two box sets, the second set for the Third Doctor continues the trend of longer stories with a single six part adventure set during the middle of Season 11 dealing with some of that season’s major themes written with a more modern sensibility from Alan Barnes.  Kaleidoscope at one point directly references similarities to ‘Invasion of the Dinosaurs‘ and while there isn’t Malcolm Hulke’s ecological message, it does deal heavily with governmental conspiracy and how the 1970s Cold War mixed with pop culture.
