I think the first two hours was her going over Star Trek, then through season 1 in detail (probably too much), then realizing how long she’d been on it and flying through seasons 2 & 3 in an hour, and then finally about 3 hours in actually getting to the title subject.

She makes some good points about season 3 being about just as dumb as the other seasons, despite being “the better” season. Having every young officer in Starfleet simultaneously assimilated by the Borg and turning on/killing a large number of older officers has given a huge number of them PTSD for years and created a large number of older officers who now hate anyone younger that turned. They hand-waved the solution and it’s just like, “Hey, it’s all cool now!”, but the mental damage would traumatize a good portion of Starfleet for a generation or more.
