I didn’t really think the Tardis was destroyed at the end of part 1 – let’s be honest, that’s never going to happen – but if such a thing were to occur, it would have to be in a far more interesting story than this, and in a manner far less mundane than being caught in a meteor shower.
Gravity is the theme here, and a race of Tractators are using it against a crashed Earth colony to smash its people with meteorites, drag them underground, and eventually turn the planet itself into a mobile home. For some reason that is never explained, the colony leaders want to control the flow of information and keep this whole underground business hush-hush amongst the colonists. Predictably, the Doctor and company are accused of being the aggressors, there’s a power struggle amongst the colonists, and frankly by this point I was bored.
There are a few things that kept my interest. Turlough recalling his ancestral memories (what?) about the Tractators, leading to a superb piece of overacting. I like Turlough; it’s as if he knows he isn’t going to be in the show very long so he overdoes everything. He’s never dull, I’ll give him that. There’s also some funny business with a hatstand, which apparently the colonists have never seen before and they think it’s a gun or something.
There is definitely potential in this idea, but it’s so blandly presented. The direction is poor, particularly where any action is involved, and the Tractators are just your typical silly-looking rubber suit monsters. The odd bit of gruesome imagery, such as the corpse of Captain Revere controlling the mining machine, goes some way to make this memorable, but nothing else resonates. A mediocre effort overall.
