Kenneth Washington ...


As Kirk, McCoy, Sulu and geologist D'Amato beam over to a geologically unique planet, an attractive woman suddenly appears in the transporter room and, with but a touch, kills Transporter Chief Wyatt. They're not quite sure who or what she is. They also find themselves unable to contact the Enterprise, which has been flung nearly a thousand light years across the galaxy. The woman soon re-appears, both on the Enterprise and on the planet, touching/killing D'Amato and Engineer Watson. While the landing party faces extermination from this mysterious woman, the Enterprise, endeavoring to return, faces possible destruction from a subtle malfunction administered to their warp engines.

In the preview trailer, the visual effect of flashing blue lights has not been added in yet when Scotty's corridor is shown. See more »


Left in charge of the ship, Mr. Spock uncharacteristically browbeats everyone on board just for being human (seemingly not free of emotions as he's always claimed). Given that he's the science officer and that the Enterprise orbits a planet whose very existence is inexplicable, it's reasonable to hypothesize that he's getting back at Kirk for leaving him out of the away mission by belittling the crew at every turn, thereby becoming a character ruled by the emotion of bitterness.

Mr. Spock: The power of this intruder to disrupt every cell in a body, combined with the almost inconceivable power required to hurl the Enterprise such a distance, speak of a very high culture and a very great danger.

one of the absolute worst!!
17 October 2013 | by (United States) – See all my reviews

It's hard to come up with many candidates for "Star Trek episodes worse than this" -- and I've seen the Star Trek V movie!

I won't even bother talking about the plot, script, etc -- they are just bad. In the same way that the "Trouble With Tribbles" episode was written to basically just be a lot of one-liners and slapstick, this episode seems to attempt to completely re-write the basic personality of Mr. Spock -- he is, in this episode, simply a sarcastic bastard -- why would the writer do this?

In every Star Trek except this one, Mr. Spock has a consistent personality and outlook, and ways of dealing with the emotional humans he works with on the Enterprise. In this episode, despite the emergency situation which is non-stop, Spock takes time out to make sarcastic comments to everyone -- not only is he sarcastic, but it seems the writer was deliberately trying to make some of Spock's comments funny (totally out of character), as he constantly misinterprets statements made by others, as if he had no experience at all with the ways humans talk.

In the "Court Martial" episode, Spock told us that "human beings have characteristics, just as inanimate objects do." Likewise, throughout the ST universe, Spock's character is totally consistent, thanks to the excellent acting by Leonard Nimoy. He must have HATED being in this episode, it's bad on every level but particularly puts the Spock character in a bad light.
