Breezes by at a Good Pace
12 November 2015 | by JamesHitchcockSee all my reviews

The Doctor and Sarah find themselves (apparently) back on Earth, in the village of Devesham, not far from a UNIT base. This serial, in fact, marked the last occasion on which UNIT was to feature during Tom Baker's tenure as the Doctor and the last appearance of Sergeant Benton. Ian Marter made a one-off guest appearance as Harry Sullivan, who had been one of the Doctor's companions during the previous season. Nicholas Courtney, however, was unavailable to play Brigadier Lethbridge-Stewart, so another senior UNIT officer, Colonel Faraday, was created to replace him.

But, of course, the Doctor and Sarah are not on Earth. They have ended up on an alien planet whose inhabitants, the Kraals, have created a replica of Devesham so that they can rehearse their plan to invade Earth. The Kraals' powers to create replicas do not just extend to buildings. They have also perfected the technology to create androids which are exact duplicates of humans, and it is these androids, cunningly disguised as real earthlings, which are to spearhead their planned invasion.

This plot line was not very original even by the standards of "Doctor Who", a series which always had a tendency towards self-cannibalisation. About the only original feature is that the above fiendish plot is being put into effect not by the Daleks, the Cybermen or any of the Doctor's other established enemies but by the Kraals, a race of beings so repulsive that they could even lose an interplanetary beauty contest against the Sontarans. (As the average Sontaran has a face like a mouldy potato that takes some doing). This was to be the Kraals' first and last appearance in the series, and I cannot say that they were ever greatly missed.

For all its lack of originality, "The Android Invasion" does have some enjoyable features. It manages to generate considerable tension though the use of the android device. The Kraals have the ability to create exact replicas, in voice as well as in appearance, of real individuals, and have even managed to duplicate the Doctor, Sarah and members of the UNIT team, which means that we are never sure whom we can trust. One critic wrote that the serial "may not be the deepest or for that matter the most original of stories told in the series but it's a fun tale that breezes by at a good pace". That would be my view as well.
