Sometimes, even though you feel a little cheated at the end, the basic premise of an episode works well enough to keep your interest. In this one, a young man has been groomed to be a human slave to a hunk of metal, an enormous ship that has the qualities of a sentient being. The young man is curious, but every time he tries to expand his knowledge, he gets "racked," that is subjected to incredible torture. He submits willingly because he has no basis for disbelief. He has always been there. The ship begins to realize that human's have a life span and something needs to be done to perpetuate the species. It brings in a female from somewhere and they are forced to couple (that is, explore their sexuality and ultimately to produce a child). The cold-blooded ship is unable to catch on to the signals that the couple is falling in love and questioning what is happening to them. They are becoming a threat to their master. There are several scenes of nudity and simulated sexual activity. The ship is only interested in one thing and doesn't realize that some sabotage is potentially at work. The story says it is in the natures of people to be free and chart their own courses, even if it brings about their destruction. This theme has been used frequently in this series. The weakness here has to do with how it all plays out. It's not bad but a little too pat for my tastes. Still, it's much less cynical than previous episodes have been.
