Good premise, but I think it was undermined heavily by the Bebe Neuwirth character demanding sex to help Riker escape. It clashed with the rest of episode's serious tone.
I thought that was hilarious!
What's wrong with a little humor? The show's supposed to be entertaining.
And anyway, that there was a moment that poked fun at a sort of stereotype of UFO believers, as well as fanbois
—and, by the way, no "serious" discussion of close encounters is complete without at least mentioning wackos—that in no way undermined anything.
