This was one of the non dalek stories written by Terry Nation, and it was certainly one of my favourites. It tapped into the same themes of paranoia which saw shows have the KGB train spies in mock up English towns. Only in this case, its aliens with androids in a mock up English town.
This was one of Baker's better stories early in his reign. The way Liz Sladen and Tom Baker played their android doubles by just a subtle variation of the way their eyes looked allowed the audience to tell which was the android and which was the real characters we know and love. It was also a nice touch to see the Doctor try to figure out what was going on with that weird English town. He came up with two explanations, including radiation contamination forcing the town to be abandoned, and when he saw the android townspeople behaving like a bunch of weirdoes, he suspects some alien presence had taken over their mind. Both explanations are wrong of course, but we already know its androids, because its in the title.
The extra features were also nice. Featuring a get together of those people who lived in that small town when DW came to film. Also they talked about the making of this episode and had some interesting continuity errors, although I didn't think it was that bad. For interest these were
1. Cavill didn't realise the Kraals had lied to him about his injured left eye, which they told him they were unable to reconstruct it. The actors mentioned that the only way for him not to realise earlier that his eye was still intact, is that he never once lifted up his eye patch, not even when he showered, shaved etc. This didn't bother me too much, since he may very well not do this, so strong was the Kraal indoctrination and it only took the Doctor to force him to confront this fact.
2. The Doctor reprogrammed his android double to attack the Kraals. Only problem with, the Doctor had generated a technobabble signal (using normal radar no less) to disrupt the android circuitry effectively paralysing them. The story had a scene which addressed this, however due to time constraints they could not film it, and were bombarded with calls from fans asking how the hell this could happen.
Again this didn't bother me so much. The Doctor mentioned he reprogrammed the android, so while doing that he obviously made some technobabble adjustments to allow his android double to function.
Final verdict - one of Baker's better ones, and I recommend it. It is available on VHS, and only recently become available on DVD here. Note that they didn't do much to fix the special effects. For examples the Kraal gun just makes a light and you see their target fall down, rather than seeing a beam strike the target like with some of the other episodes. I don't mind this too much, it gives the impression that various Who aliens have different weapons, and can convey this better than if each alien fired a beam weapon of different colour.
