A fine little FCBD affair, but this doesn't really do much for me.

Twelve reads a bit mean in this story which I wouldn't expect of a Season 9 Twelve... Then again, he's travelling on his own, could see this being just post Season 8. Even still though.

The art of the K2 robot is really fun, and I do love a good callback, but I think it's dispatched far too easily and there's not really any tension, it's hard to have any in a short like this, but that's why these stories often go for humour or something else, or devote more time to taking down the threat.

There just isn't much to grab me here beyond the 'Hey look it's that thing I recognise', which, to be fair, it is that thing I recognise, and that is fun, but that doesn't work on it's own.

Also Osgood says that the K1 incident was towards the beginning of his 'Third Incarnation'. Could read that as being because UNIT never met One, but at the very least the Brigadier met him in The Five Doctors, so it just feels like a really strangely out of character moment for Osgood.
