A fairly harmless story which sees 5 and Adric land on a planet that shows them their worst fears. The characterisation isn't bad, but nothing happens that really makes the story stand out, and the nature of the planet is fairly clear from the start (especially given this story's title), so it's difficult to rank this story highly.

What's funny is (Psychodrome spoilers) this is the second time in a week that Adric has had to deal with oversized insects and arachnids created from his fears, according to TARDIS.wiki's timeline for 5
