Voyager Twist to Some TNG Plot Recycling
10 September 2016 | by sirdscoastSee all my reviews

Oh Star Trek, how I love you, but after watching nearly every single episode of every incarnation, you start to notice not just a few episodes share very similar plots. It is fantastic in a sense as each show had to produce 20+ episodes a season and we were not in the singular season arc most contemporary shows such as Game of Thrones, Arrowverse, and the sort currently produce. Different facets of humanity were explored or actors were permitted to explore their characters and experiment with their own acting abilities. This episode is strongly reminiscent of the TNG episode "Schisms", which was also creepy in its own right. Kudos to the writers for giving thought to individual story lines such as Seven continuing to learn about working in a hierarchy or Tom and B'Lanna pursuing their relationship. Both Schisms and Scientific Method treat the episodes as mysteries, with the crew finding a way to counter the threat by relying on each other's unique abilities to save the day. When I was younger, as much as we love Trek or even hero-worship, it made me wonder if similar events happen to other species' crews and if they were equally successful? I think my younger self was beginning to find certain episodes where the crew always have a convenient solution to an uncanny problem a bit too convenient. Its like every superhero movie every made: villain wants to destroy Earth, hero saves the day, gets the girl. Especially in these Marvel and DC expanded universe times, if you have seen it at least 5 times with 5 different heroes, you kind of have seen it all. :) Now that I am older and am coming around to watching Voyager again for the second (or third) time, I see that each show's crew has a higher chance of several because of the unique traits each character possesses. A purely human, Vulcan, Klingon ship may also find success, but not as quickly as the TOS, TNG, DS9, VOY, or ENT crews. In this case, had Seven not been on board, it might have been possible to adjust the doctor's field of vision as in the episode "Displaced", but Seven seems to be a more convenient choice. Star Trek's core message of inclusion and celebration of diversity rings true even here, without the straightforward, written message directed at audiences. As a species, we are more likely to survive and evolve if we treasure each other and rely on each other. As much as I don't like plot recycling, it was a decent episode focusing on how Voyager's crew handles similar experimentation as TNG once did. Oddly enough, I don't remember a similar episode in DS9, but I could be wrong! Enjoy!
