Possibly confusing it with "Mortal Coil", with its traumatised Neelix on the verge of suicide? That's a decent episode for the character. Where his new found disbelief in an afterlife, spills over into the bedtime stories he's giving to Naomi. They took Neelix there again all-too briefly for "Memorial" IIRC. "Once Upon a Time" is like TNG's "Cost of Living", emphasis on the holodeck as 24th Century Children's entertainment. Kind of strange, given nobody of that target age would be watching. You have that onscreen for a while, maybe as a C-plot. Answering the question, what families do on starships. But focusing whole shows purely on it is a massive turn off. To me anyway.
