A typical Briggs base under siege story. Not a particularly special story, but filled its purpose well. I quite enjoyed Alison and Leela's interactions, and though she didn't have an awful lot to do, Leela was never treated by the narrative as stupid which I appreciate. It is also interesting to me how often a Briggs script is very anti-empire. Here, British Empire is treated as savage and base - something that Leela is explicitly not in this episode. The British pillaging the alien ship and taking it to dominate the alien culture is very much treated as a bad thing in this script, so despite the generic plot beats, I still enjoyed the story overall as it made me think, which is better than being boring.
