I hate Seven of Nine now
When the show first ran, I thought she was a great addition to the cast. Looking back on it now in reruns, it's embarrassing how much she completely changed the dynamic of the show at the expense of other characters on the show, especially Captain Janeway, Tuvok and B'Elanna Torres.
She is the epitome of a Mary Sue character (not in the way that that moron, Max Landis, means). By Mary Sue, I mean that it was so obvious that her producer-boyfriend was enthralled with her that most of the story lines either had to be centered around her or whatever problem that needed to be solved only solvable via her "superior" Borg intelligence. Literally, more than half the storylines in which the ship was in danger almost invariably involved needing Seven of Nine in some way, sometimes overtly, sometimes subtly. It got to the point where it was like, "Well, why even bother with Engineering, when it always falls short of that one thing preventing it from fixing the ship that can only be completed without input from Seven or her Borg technology."
In the beginning, this plot point made sense because it helped make Seven--a completely new cast member--become integrated into the show in a way where she felt like she served a real purpose. But then it got overused, which is why the writers had to hook Torres up with Tom and turn her into brood mare to make up for the fact that she was basically rendered useless as a character.
Her relationship to Janeway completely fucked up the brewing relationships between her and the other crew members. It was clear that Tuvok was becoming her most trusted friend and there were feelings for Chakotay. All of a sudden, Janeway was reduced from female captain in complex relationships with male subordinates to practically being chained to Seven all the time because of her stupid bratty rebellious meltdowns and inability to cope as a liberated Borg.
And that catsuit looks more and more ridiculous with time. Really, was it necessary? It looks so stupid, as stupid and cheesy as the "sexy" outfits from Mod Star Trek. It dates the show so badly now precisely because no one thinks that that type of outfit is "sexy" anymore than anyone thinks that the gogo boots, cut out minidresses and metallic fishnet stockings of the 1960s are sexy.
