I thought it was a good typical silly Red Dwarf plot in the end, and a very easy obvious kind of thing for them to choose for a special episode. I thought the whole thing though was very slow and low on laughs to go with the plot. Certainly the characters seemed a bit off for me as well, Lister was not as funny or stupid, Rimmer was not as smug or cowardly, the Cat wasn't so cool. It could have been much better if it was condensed to just a normal 30 min episode or possibly 2 episodes!
