Set in a futuristic Britain ravaged by eco-logical disasters, Nebulous manages to find a surprisingly rich vein of comedy in this dark scenario. The series is rich in parody and satire on science-fiction (the entire second episode is an extended parody of the Doctor Who episode "The Claws of Axos" - unsurprising given that most the cast and crew previously worked on Doctor Who), and the dialogues (and in many cases, rambling monologues) are sharp and clever. Overall, Nebulous is perhaps the best radio-sci-fi-comedy since The Hitchhikers Guide to the Galaxy, and certainly the most consistent.
