Aliens from the Andromeda Galaxy known as the Kelvans capture the Enterprise and refit it with advanced technology for a 300 year long trip back to the galaxy of their origin. The reason? After assuming human form to exist within our galaxy and to understand it better for conquest, the Kelvans need a human craft that will sustain their lives and the lives of their descendants as they continue to complete their mission. With his crew incapacitated, Kirk manages to use the Kelvans new humanity against them by irritating them or using human emotions they are unfamiliar with. His point is to show the Kelvans that they are no longer Kelvan but as human as the crew of the Enterprise. Kirk manages to convince them to settle on the planet they were discovered on. They agree to this and all ends well. But given the Kelvans superior technology and celestial navigation, dont you think this is an episode worthy of following up on? This is a plot line that demands revisiting; even its just to help them build shelters and other amenities of life necessary for colonization. After all, as in Space Seed, we dont see Kirk leaving the settlers with anything. In fact, this would have been a great TNG episode, with Captain Picard following up on one of the classified mission logs of the original Enterprise. Heck, they could have even been included in a cameo appearance as weapon specialists or some sort of advisory role. This is a plot line that needed further exploitation and would have certainly won nostalgia points with the die-hard Trekkies. What a waste.
