Did Star Trek: Voyager just repeat The Doctor's storylines with Seven of Nine?

In every Star Trek series, you have your standard archetypes. Your commanding officer, your "Spock-like", your doctor, the chief of engineering, your youthful type, your rogue, your stoic type, your comedic relief, and usually the understanding one. Every show has one of these it seems. Maybe not as consistently with the Nu Trek of it all, but there's a reason why the newer shows aren't warmly embraced. They deviate too much from the established norm.

Yet, Nu Trek wasn't the only series that shook up the standard. Star Trek: Voyager did just that. Originally, the show had its commanding officer, Captain Kathryn Janeway. They had their stoic type in Chakotay, their rogue in Tom Paris, and their youthful aspect in Harry Kim. The Chief of Engineer was there in B'Elanna Torres, as was the "Spock-like" in the holographic EMH (emergency medical hologram) The Doctor. Kes was your "understanding" character, while Neelix was your comedic relief.

Only Tuvok was left out of the loop, though he was both the stoic and Spock-like type. He was also a firm believer in security, maybe more than most. Thought he was a sub-characteristic. The fact he didn't have a primary one is why his character often felt flat.

Yet, the call would be made to remove Kes and replace her with Seven of Nine, another "Spock-like". Like The Doctor before her, Seven of Nine had to learn to find her emotional center. The Doctor struggled to grasp his emotions until he further expanded the parameters of his program to help him better relate to his corporeal patients.

Seven of Nine would have to relearn how to embrace her emotions in a healthy way, thus reattaching to her human side. A process that took most of her time on the series. In doing so, she followed a similar beat to that of The Doctor. Both had to learn/re-learn human interactions, customs, and proper behavior. Both explored the concepts of dating and all that went into it, and both also explored how a more mechanical being can come alive when introduced to concepts like art.

While I adore Voyager, it's fair to say that they just repeated The Doctor's storyline with another character. Both Seven of Nine and The Doctor went through an evolutionary process on the show, one that mirrored both of their experiences. It seemed to feel like the more The Doctor grew, the more human he became and the more necessary a character like Seven of Nine became.

No longer was The Doctor unable to relate to his fellow crew members, and so the show needed a new "Spock-like" to come in and be that foil for the show. In doing so, Seven of Nine repeated similar story-beats that The Doctor already went through and honestly, it made the show all the better. Star Trek needs that distant outsider. It works better when there's someone who doesn't grasp the concept of humanity and has to see it play out.
