The Invasion

Premise: The travellers land in London where they agree to help find computer scientist Professor Watkins and discover Brigadier Lethbridge-Stewart is also investigating disappearances.

Notes: There was originally going to be a scene where UNIT rescued Professor Watkins from the IE car which was escorting him. However, it was cut because of the budget so another scene was written to replace it where Gregory (who would have been shot in the attack) describes the attack instead and is subsequently killed by the Cybermen.

Verdict: An amazing thriller with an great villain in Vaughn and another great performance from Troughton. It doesn't feel padded out at all, contrary to belief that it is overlong. Although lacking in Cybermen, the moments that do have them in are chilling and the music is really amazing all the way through and really does create a good atmosphere. This is the Cybermen's finest hour with only a few minor flaws here and there 10/10

The Web of Fear

Premise: The Doctor, Jamie and Victoria discover that Yeti have invaded the London Underground.

Notes: This sequel to The Abominable Snowmen features the first appearance of Colonel Lethbridge-Stewart (later Brigadier) played by Nicholas Coutney who would go on to appear in many more stories up until the shows cancellation in 1989. Jack Watling also returned as Proffessor Travers with heavy makeup to make him seem older than he was in The Abominable Snowmen. London Transport denied permission to film in the real London Underground so they were forced to create sets for the studio. These sets were so believable that London Transport complained that they had filmed on their property without permission.

Verdict: A hugely atmospheric tale set in familiar but somewhat ominous surroundings. The Yeti are surprisingly menacing and the climax of the fourth part is simply unbeatable. It's just a shame that after this it begins to slip 9/10
