No, that one didn't bother me, it had a happy ending.
I usually don't mind "What is Reality??" episodes in science fiction and fantasy because it's usually made clear in the end that the alternate reality was not real. What made me so upset about the Buffy episode the fact that they didn't make that distinction at the end, and instead implied that the reality of the whole Buffy series was in question.
When you're really invested in a series, tossing something like that into one's brain is just cruel! I have a well developed ability to suspend disbelief and just absorb a story, but throwing out the possibility that the whole series is
the product of a psychotic girl's hallucinations
is just messing with the audience's head. And Joss Whedon did it deliberately!
I don't need my head messed with, thank you very much.
I did like that the "Gamekeeper" guy was the person that played Lt. Barkely in StarTrek Next Gen.
It made me smile.
