Finally got round to seeing this episode after a particularly long day at work. I'm so pleasantly surprised. I'd worried that Samsara would prove to be the pinacle of the series, and would have been fine with that. But each episode this series has improved on the last. The 'Captain Bollocks' and 'rimshot' gags didn't feel right for Dwarf, yet I still enjoyed them. The marvelously creepy villain, an entity which was both original yet a scary parody of movie villains, something at which Dwarf excels, was criminally underused. And I fear the kidneys paradox is a genuine plot hole. Kryten at least should have realised that Lister could not have his kidneys removed if they removed them in the past. The fact no attempt was made to deal with this issue in the episode makes me question, almost, whether Doug noticed the inconsistency, though that would seem too rudimentary a mistake for Doug. But I loved the episode more than the previous two, and I look forward to another watch.
