Great example of Pertwee era 'monster threatens the Earth' format.
29 September 2014 | by (South Wales, UK) – See all my reviews

Review of all 6 episodes:

The Master teams up with reptilian creatures who have been dormant under the ocean for millions of years to try to conquer humanity (again). These creatures, which are dubbed Sea Devils by terrified humans, are relatives of the 'Silurians' or as The Doctor re-names them Eocenes. They were on Earth before humans and want to claim the planet back after eons of suspended animation in the ocean depths. The Doctor tries to broker peace whilst The Master whips up a war. Human leaders also have the appetite for war so trapping The Doctor in the middle.

This adventure is not flawless but provides superb entertainment and iconic scenes throughout. The first two episodes and last two episodes of this adventure are terrific fun, exciting, interesting, well written and acted with only very minor faults. Whilst the middle two parts are slightly more flawed as the story is marginally stretched over 6 parts, they too are really good. The interest and quality levels never drop below 9/10 and this epitomises Pertwee era Who.
