What can I say about The Man Trap? As an episode of Star Trek in context of the entire series, it's a less well done note in one of the melodies that makes Star Trek what it is. It's not bad, it's not good, and it's not exactly necessary.
I'm surprised this was chosen as the first episode to air over the second pilot, Where No Man Has Gone Before, because this was such a formulaic monster-of-the-week episode. Then again, it had a good old pew-pew laser fight, nice shots of the ship, a Spock-is-an-alien-lol moment, some crewman hijinks, a Rand appearance, a desert planet, some redshirt deaths...in short, all the ingredients are there for a solid TOS episode; it's just not a very interesting TOS episode.

These guys are the Beavis and Butt-Head of the Enterprise.
The most interesting thing about this episode was the salt vampire. Dialogue alluded that it was part of the race that built the ruins Crater was investigating, but I wonder if they weren't what destroyed that civilization.
See, I know we humans require a minimum of sodium to survive (cats and dogs require significantly less from external sources, if any), and I would guess that these Salt Vampires (or M-113 Creature if you want to get technical) evolved on this planet where salt was readily available, likely in the form of salt water; the star got hotter or something happened to dry up the seas, but the creatures persisted (they probably weren't building rockets but the ruins are evidence of culture and society) on the residual salt pans and deposits left by the evaporated seas until the end, one sad, desperate creature driven by instinct.
Oh, except they're also psychic and can suck salt out of people's bodies...maybe sodium in this ecology like...carbs do in ours? I'm not a nutritionist, I just want to Watson up a history for this creature beyond "they did a vampire episode in space."

It is an effective vampire story, and from that angle I was able to enjoy it on its own merits. I spoke to some people and they put the creature itself in context; apparently this thing was scary as fuck back in 1966, and I suppose I can compare that to my own experience with The X-Files as a child - namely, a little monster named Flukey.

The resemblance is somewhat uncanny
I felt like this episode may have been chosen as the first one because the characters were all there - Sulu, McCoy, Uhura, Kirk, Spock, Scotty, even Rand - all the characters one thinks of when they think about classical Star Trek. They're also more or less in their proper form; Uhura flirts aimlessly with Spock (who is visibly annoyed), McCoy is cantankerous, Kirk utters out a fortune cookie navel-gaze at the end, Rand is a secretary. Where No Man Has Gone Before had Spock smiling (and being a smart-ass, which is in character but he was a grinning jackass in that chess match), some old fart doctor, and no Uhura; Charlie X had Spock smiling as well, but I rather liked the coy smile he was giving Uhura as he strummed his lyre.

I wonder what the Kelvin version of The Man Trap was like...
Finally, I can't help but wonder what a post-Devil in the Dark Kirk and Spock may have done with this creature; would they shoot it, or would they try to reason with it, offer it salt until they could get it to some sort of starbase or planet capable of supporting its needs? If they can make Pluto in less than 9 minutes, they can surely get mass quantities of salt for an alien. You know Picard would have had Worf and Data wrestle it to a replicator and start force-feeding it all the salt it could consume.
Personal Rating: 2/5; skip.
It's not a terrible episode, but there's nothing here that other, later episodes don't do much better. I'd suggest finding the scene between Spock and Uhura on youtube, or watching only the scene simply because it's a good establishing moment for Spock.
END.
