Synopsis: Crew members are tired again! Dang you REM sleep!
Memory Alpha Summary: Not as well-written as Cartman Gets an Anal Probe
Review: While Data’s poetry reading (Ode to Spot) makes for an underwhelming teaser, it’s quite clever and hilarious, not to mention a little touching. One would think that the crowd would have enjoyed it more.
As for the mystery, it doesn’t quite all come together. Some weird shit goes on, then the episode picks up steam when the four officers come together in the holodeck to recreate their memories. But then when we actually see Riker awake in deep subspace, he’s there for about sixty seconds and the aliens are…kind of lame. Then we get a teaser like we did at the end of The Neutral Zone, yet we never see these aliens again. In this case, no loss.
Death By Troggles 
You know what, Ode to Spot is the best part of the episode. So here it is for all to enjoy.
Felis Cattus, is your taxonomic nomenclature,
an endothermic quadruped carnivorous by nature?
Your visual, olfactory and auditory senses
contribute to your hunting skills, and natural defenses.
I find myself intrigued by your subvocal oscillations,
a singular development of cat communications
that obviates your basic hedonistic predilection
for a rhythmic stroking of your fur, to demonstrate affection.
A tail is quite essential for your acrobatic talents;
you would not be so agile if you lacked its counterbalance.
And when not being utilized to aide in locomotion,
it often serves to illustrate the state of your emotion.
O Spot, the complex levels of behaviour you display
connote a fairly well-developed cognitive array.
And though you are not sentient, Spot, and do not comprehend,
I nonetheless consider you a true and valued friend.
Here I’m going to have to disagree; Schisms is one of my favorites Top 10? Could be. Creepily dark.
And a DAMN sight better than Justice.
top 10? Dang.
I admit, the scene in the holodeck creeped me out. But I felt the climax was such a let down.
Let down? yeah, I suppose.
Finding someone whose blood was replaced by plastic (or whatever) is nicely done; not a person (sorry, MANNEQUIN) half-way through the floor, but still
