A pretty inoffensive two-episode story. It's a nice change of pace to get the rare story that's filmed entirely outdoors in some scenic rocky terrain. The first episode doesn't do much with us meeting some stranded astronauts with a machine following them. It picks up more when we meet the Sontaran, but the story consists of a lot of 'Sontaran pops up with these characters, then with this characters, etc'. The Doctor tiring out the Sontaran is pretty fun. Overall, an inoffensive story but nothing memorable.

I don't hate this story. It had a decently interesting premise, the main cast were on form... but the whole thing felt so utterly uninspired in terms of script and direction. The most remarkable thing about it is the fact that it's only two episodes long and it still feels padded. 6-and-7 View profile Like Liked 0 Show All Reviews (9) Open in new window Statistics AVG.
