Did You Know?


The plot point about Kukulkan actually being an alien lifeform was inspired by the Erich von Däniken book Chariots of the Gods?, especially claims like Indian sites in Peru having actually been created by aliens as methods of communication. See more »


When the Enterprise is under attack, Uhura suddenly is coloured white in a wide shot. In the same shot, we see a lieutenant's stripes on Ensign Walking Bear's sleeves. See more »


Dr. McCoy: There's a line from Shakespeare...
Captain Kirk: Yes Bones, I remember it: How sharper than a serpents tooth it is to have a thankless child.
Mr. Spock: Indeed, Captain.

A poor remake of "Who Mourns for Adonis?"
19 April 2015 | by MartinHaferSee all my reviews

If I were to pick one of the original episodes of "Star Trek" to remake or rework for the cartoon series, one of the last ones I'd ever consider would be "Who Mourns for Adonis?". It was clearly a sub-par and rather embarrassing episode where the Greek god, Apollo, captured the Enterprise and brought some of the crew down to his planet in order to be worshiped. Yet, someone DID decide to do just that--and they managed to make the plot even a bit stupider!

When the show begins, Mr. Sulu is NOT at the helm--so you know that there is some reason for this. Sure enough, when a weird spacecraft arrives and takes hold of Enterprise, this never before or since seen crew member just happens to be in the right place at the right time. He is the only one among the crew that recognize their captor. It's Kukulkan (also known to the Aztecs as Quetelcoatl)-- the Mayan bird/serpent god!! What follows is just stupid.

While many episodes of the old cartoon series are decent plots marred by bad animation, this particular one doesn't even have a decent plot--just bad animation and a re-tread plot. The only thing I liked was some of the dialog but that isn't enough to make this one worth recommending.
