My twin and I are massive Red Dwarf nerds, knowing practically every script by heart, so the usual online quizzes don't do it for us. This book really challenged us! The writers clearly did their research.
We focused on the written questions but there are crosswords and wordsearches and such too! Even self-filled fact files from the cast and crew (R.I.P. Rob Grant 💔). Some questions even focus on the two novels (which admittedly we haven't read in years) and we only really found the narrowest most pedantic of mistakes in the answer pages.
We loved the contrast from easy questions like who removes Lister's second appendix, to naming exact Space Corps Directives by their numbers. Matching guest stars to their characters and the "who said this?" sections were great also. Lots of laughs were had. Can't wait to do the next one!
