I have a hard time getting over the thing where the story introduces some amazing new capability, and it’s never explored further. In this one it’s, “we found a way to get home instantly, but we’d have to do a thing in sick bay to reverse the side-effects.” A similar case is the episode with the planet of friendly hedonists with long range transporters that it turns out they can’t use because “the power systems are incompatible”.

I’m sure if I weren’t so uptight I’d enjoy these episodes more.
