Storyline

The Enterprise is sent to investigate the disruption of the Gamma VII-A solar system and the destruction of the U.S.S. Intrepid, staffed solely by Vulcans. When they arrive they find a large dark mass floating in space that is draining energy from everything around it, including the Enterprise. Drawn into the mass, they find a huge amoeba-like creature and Kirk must decide which of his two friends, McCoy or Spock, to send into it aboard a shuttle craft on a mission of no return.

Trivia

The giant space amoeba the Enterprise encounters measured over 18,000 kilometers in length. For comparative purposes the planet Earth has an average diameter of just over 12,500 kilometers. See more »

Goofs

When the Enterprise enters the body of the organism, there is a violent impact which knocks Uhura and her chair to the ground. The camera cuts briefly to the Enterprise inside the organism, and when it returns to the crew just a moment later, Uhura is still sitting in her upright chair as if it never fell over. See more »

Quotes

Mr. Spock: It's logical to assume that something within this zone absorbs all forms of energy whether mechanically or biologically produced. Whatever it is, it would seem to be the same thing which drew all the energy out of an entire solar system and the Intrepid.
Capt. Kirk: The same thing, not the zone itself?
Mr. Spock: I would say not, Captain. The analysis of the zone indicates it is a negative energy field, however illogical that may sound, but it is not the source of the power drain.
Capt. Kirk: Maybe it's a shield of some kind, ...

Trek does "Fantastic Voyage"
11 March 2011 | by (The San Francisco Bay Area) – See all my reviews

I usually watch the episode and read a few other reviews before extolling an opinion. I also usually contemplate what might be the "inner story" of whatever it is that's bubbling under the surface of the plot.

But not this time.

This episode feels pretty contrived, but still entertaining in a science-fiction sort of way. At the time colored oil effects at dance parties were just coming into vogue, and it looks like the creative powers took that discovery and injected it into an episode of Trek. Essentially what was happening in culture at the time was young hip people were purchasing colored oil at the time and putting them on clear plastic sheets on overhead projectors during dances. They would then manipulate the colors by jostling the sheets. Well, here we have an amoeba incarnate via that bit of cultural artistry.

Beyond that there isn't a whole lot to say about this episode. We see Kirk struggle with decisions, and we get the usual passionate verse logical persona conflicting for the task that will save ship and crew. We're also treated to a bit of an homage to "Fantastic Voyage", where a miniature sub and crew are injected into a human body. Trek does something similar, but blows stuff up to colossal proportions to utilize the same theme; i.e. the amoeba is titanic in scale, verse the Enterprise being shrunk to explore one.

It's a good simple adventure yarn that passes the time. Not really a sterling episode, and somewhat worthy of a smirch, but Trek fans like myself will watch to pass away the hour by spending time with some of our favorite fictional characters.

Give it a shot.
