Tsunkatse pandered to a different fan base not to a broader audience. And it was the exception, not the rule. What did Voyager actually do to grow the fanbase? The Next Generation was a pretty cutting age show for the late eighties. However, Voyager just kept fetishing that model of storytelling into the twenty-first century. It added a sexually objectified female character, but that was pandering to what it perceived to be the target market - nerds who like boobs. I love Jeri Ryan's performance, and like her character arc, but the addition of Seven as the new focus character was the point at which it was clear this was not a show that saw itself aiming towards a broad audience, but towards shut-ins who think "sexy" is a painted-on catsuit. (Whatever about the infamous "male gaze" scene in Into Darkness, it was a single short scene, and had an accompanying "female gaze" scene with Khan in the shower that was unfortunately cut.) By the time that the first two seasons of Enterprise had committed to doing "what TNG had defined as Star Trek stuff" with "awkward sexy stuff because nerds like boob, right?", the franchise was terminal.
