In the past, Red Dwarf has been 80% comedy 20% story. Episodes were mostly unlinked from one to the other, so the basic premise was a situation that set up the comedy. From the start of series 7 onwards, this percentage changed. Personally I think Series 7 had the right balance of story and comedy. Back to Earth on the other hand, is 90% story 10% comedy. The situation no longer sets up the comedy - the comedy is injected into the story, with mixed results, I would say a negative result. Did that mean the thing was bad? No, it doesn't. The story was really really well done and very clever, with suitable twists and kept everything thinking and talking. So props, the script was excellent. But the humour lacked. The jokes weren't there, at least not in the form they used to be. The only one that really felt good was the Lister bathroom joke and when Rimmer killed his nemesis. So I think, it was good in one way and bad in another. What needs to be remembered is why Red Dwarfers watch the show. Is it because of the story? No, it's because of the weird situations and the comedy. Question is, does Red Dwarf want to be a humourous drama, or a pointless sitcom. I'd love for number 2.
