A strangely unsatisfying first parter
27 April 2008 | by (England) – See all my reviews

There's something missing from "The Sontaran Stratagem". While the use of sat-nav devices to evil effect is inspired and reminiscent of something like "Terror of the Autons", the episode somehow fails to inspire.

There's something very un-Sontaran about the whole affair. The menace here is Sontaran-lite, just as I was bitterly disappointed with the return of The Doctor's silver nemesis in Season 2. Perhaps it's me but while the make-up is wonderful (the early close-up of the Sontaran is excellent), the costume looks like something from a '90s Action Man.

Donna remains the strongest companion to-date, making Martha look rather lightweight in comparison.

7 out of 10. Only the first part of this double-header so things may improve but this is a very average tale so far. At the end of the day, Helen Raynor just doesn't deliver the quality of scripts that you expect from this series. It's missing fizz and pop and, overall, disappoints.
