Invasion of an old enemy in a story of the very highest standard .

Review for all 8 episodes:

This is a truly classic story of the Cybermen invading Earth with the help of megalomaniac businessman Tobias Vaughn played brilliantly by Kevin Stoney. The villainous Vaughn is a superb character, performed to perfection and is actually the main adversary for The Doctor with the Cybermen very much in the background. This is not a bad thing as the Cybermen when they do appear have more impact and do their job as a 'monster' perfectly (especially in iconic scenes rising from the sewers to be seen starting to position themselves at locations such as St. Paul's Cathedral). Menacing, exciting and entertaining. Meanwhile Vaughn does his job perfectly, intellectually and verbally jousting with The Doctor better than any Cyberman really could.

To keep such quality up over 8 episodes is very impressive and it does so with cleverness and style. This is an all time classic, one of the greatest. It is a wonderful blend of great acting by regular cast and guest cast, characterisation, dialogue and direction (by Douglas Camfield). It has a good helping of action, tension, an intelligent script and is top notch storytelling from writers Sherwin and Pedler. Great stuff! All 8 episodes 10/10.
