Review of all 4 episodes:
This 4 part story sees the return, in a modified form, of the Cybermen which is welcome and successful. This time they are attacking a weather control station on the Moon in the year 2070. I am in the minority who preferred their original voices to the ones they have here but other than that they are improved upon. They maintain their appeal and unfeeling, chilling character but are a bit more sleek and high tech. Their plans, and therefore the plot, are similar to the first Cyberman story in many ways and the quality is mostly not far below that brilliant first Cyberman story either. It is generally great entertainment.
A few less successful ideas and imperfections occur but it is very very good despite that. There is great suspense and some superb scenes of dialogue and action.
The regular cast are on good form and this story helps to cement the Cybermen as one of Doctor Who's most iconic 'monsters'.
My Ratings: Episodes 1 & 3 - 10/10, Episodes 2 & 4 - 9/10
