“Descent, Part II” is a total mess of an episode which destroys both the character of Data and the Borg, while “Liaisons” manages to be both lazy and ungenerous. If there’s a worse pairing of episodes in the entire Star Trek franchise, we’ll find out, but we really, really don’t want to. Plus! Would a spinoff featuring Lore and Thomas Riker be better than Star Trek: Voyager?
