Query: Artificial companion.

If this had been made a few years later in Tom Baker's years as the Doctor, it would have been far by the best adventure of the season, but in the classic-filled years of Hinchcliffe/Holmes, it comes across as pretty ordinary.That's not to say it's a bad story. On the contrary, it's very enjoyable and filled with nice touches of humour, not to mention memorable scenes such as the sinister android version of Sarah, the return of (most of) UNIT, good location work, the rhino-faced aliens and the plan to replace human beings with mechanicals. Don't expect a classic adventure on the same level as 'Pyramids of Mars' or 'Genesis of the Daleks', but you won't be disappointed either.
