As slainmonkey says, DNA does seem to stray into silly territory at the end. There are some great bits though, but for me the stand-out bit is the beginning, when the crew are attempting to dock with the ship and then are thrown into confusion when suddenly the console goes dark - before realising the Cat has unplugged it in order to use his hair dryer. I think Kryten trying to get used to being human didn't go on long enough, but then they did have rather a lot to fit in. It could easily have done with a few more scenes. Perhaps getting rid of Rimmer trying to create a copy of himself for one?
