The Pirates of Orion
A deadly virus attacks Spock but the drug he needs is in the hands of a supposedly neutral race of raiders, the Orions. Kirk races against time through an exploding asteroid belt.
This somehow feels more like a TOS episode than TAS, but not very much fun. All the plot devices have been used before and can't generate much interest on their own. We know Spock will be fine, and that Kirk will do everything to make sure of this. The Orions have been seen before, the females several times (they would be the green dancing girls) and one male in Journey to Babel, though he is disguised as an Andorian. Still, these animated aliens look quite silly and nothing like the humanoids of the live-action episodes. Also, their name is not pronounced correctly. The stress of "Orion" should not be on the first syllable as in Oreo cookies, but on the second. I'm also confused by the drug: stokaline, strobaline, strokaline - what the heck is this stuff? In the TOS episode By Any Other Name, there is a readily available drug called stokaline, but no one can pronounce it here, and it's become scare. One is forced to pick apart minutiae when proceedings get this slow.
Spock Saves the Day: Spock provides a reason to find boring pirates.
Oops: He also falls ill with a rare disease. Not really his fault.
Developments: Spock is absent for most of the, ahem, action. His dialogue could practically have been assembled from other episodes.
