Another one of those episodes that makes you google the central character because you think you've missed an episode or are slowly becoming senile. And then you realize that the writers have once again come up with a completely new crew member that you've never seen before (like in the episode "Latent Image"). And even worse: this crew member is then attributed with profound plot elements. For example that she has been a close friend of Harry Kim since they were at the academy together.
The big weak point of Voyager is, that although 150 crew members are crammed into a sardine can for seven years, only 9 of them are in focus. The nameless rest is only allowed to walk through the corridors or sit in the mess hall as extras. To this day, for example, the doctor has not managed to find a replacement for Kes in sickbay. With Paris, one of the main characters also has to serve as a nurse. Other blue, yellow and red shirts are only allowed on away missions when someone is needed to bite the dust. One wonders why Voyager has such a large crew when literally everything that happens in the series is done by Janeway, Chakotay, Tuvok, Paris, Kim, Torres, Neelix, Seven and the doctor. Even characters who get a little screen time every now and then, like Vorik or ensign Wildman (Naomi's mother), are only seen sporadically.
The story of the episode itself isn't bad at all. Lyndsay, this woman in question, who apparently hid on the ship for 6 years and then died in an off-screen mission, was resurrected by a species who then genetically modified her into their own species - the only way for them to reproduce. Since you have absolutely no connection to this woman as a viewer, it is completely irrelevant in the end whether she is alive or not, whether she is human or not and whether Kim gets his second chance or not. If you had already gotten to know this person in the previous episodes, you would have been able to grasp the moral conflict: whether this woman is the same as she once was or a newborn being who only has some memories of her former past.
And why does the universal translator sometimes translate foreign languages and sometimes not? It translates everything this woman's so-called father says in Kobali. But if Lyndsay speaks a mix of English and Kobali, it won't be translated properly. In addition: How does the translator actually manage to translate nested sentences simultaneously even though you can't yet tell what the speaker actually wants to say? And why is it even lip-synced at the end? Questions upon questions...
