Capt. Kirk: Captain's log, stardate 5843.7. The Enterprise is in the grip of a raging epidemic. Three crewmen have died and twenty-three others have been struck down by Rigelian fever. In order to combat the illness, Dr. McCoy needs large quantities of ryetalyn, which is the only known antidote for the fever. Our sensors have picked up sufficient quantities of pure ryetalyn on a small planet in the Omega system. We are beaming down to secure this urgently needed material.

Forbidden Planet/Tempest Redux
10 May 2014 | by (United States) – See all my reviews

Kirk, Spock, and McCoy beam down to a planet to get a substance to fight a horrible disease that has a foothold on the Enterprise crew. Upon arrival they are encountered by a robot that looks a lot like that Nomad thing from another episode. It is really kind of a disappointment (you can see a string holding it as it wiggles around) but I've learned to ignore this kind of stuff. The thing shoots at them, apparently trying to get them to return to the ship. The robot is soon joined by a handsome, grey haired man (Flint, played well by James Dailey), dressed in sort of a classic ancient Roman outfit. They tell him that they need ryetalin to treat the crew, but he refuses their request. They are ready to take what they want. The man relents and invites them into his home. In the home are art masterpieces and priceless antiques. He tells them he will have the robot process the serum for them. In the meantime, we are introduced to a beautiful young woman who is supposedly the ward of Flint. She apparently has the intellect of one with numerous degrees. She looks forward to discussing some esoteric topics with Spock. The sad thing about this episode is that Kirk comes off like an invasive jerk who is having trouble keeping his pants on. They are on a mission with a serious deadline to try to save over 400 people. What does Kirk do? He slobbers all over this young woman, ignoring his agreement to mind his manners. We are supposed to be sympathetic to him. Spock and McCoy are working their butts off to do their jobs while he moves around like some hepped up cocker spaniel. Still, the episode is remindful of the classic Forbidden Planet which is actually based on Shakespeare's "The Tempest." Probably the last decent episode as the series dies an appropriate death.
