I don’t care in the slightest that Zoey wasn’t the Mother. I care that she was both an unfunny character and a fairly unpleasant one, someone who was selfish and manipulative and completely destructive to the harmony of the group, and yet someone the show largely let off the hook for all of that. Even in this final episode, Robin had to couch her instructions to Ted with a “We love Zoey, but…”-style softpedal, which is nonsense. Zoey was horrible. Even her real reason for wanting to save the Arcadian was horrible, revealing her once again to be a hypocrite motivated not by ideals but purely self-serving motives.
