Storyline

Captain Kirk is haunted by a creature from his past when conducting a mining survey on a planet. He first encountered it as a lieutenant aboard the U.S.S. Farragut and blames himself for freezing in a moment of crisis, causing the death of many crewmen. The creature is a cloud-like, gaseous being that lives on the red blood cells found in humans. Obsessed by his desire for revenge and to erase the memory of 11 years ago, he pursues the creature relentlessly, putting in jeopardy an assignment to collect essential medical supplies.

Trivia

In the medical records library between Spock and McCoy, there is a large object which looks like a vertical DVD rack. The same large object was in Harry Mudd's laboratory in Star Trek: I, Mudd (1967). See more »

Goofs

At the hearing, Ensign Garrovick describes the creature as being "several cubic meters" in size, but his distance as "about twenty feet away," mixing two different systems of measurement. It's unlikely that people in the Trek Universe would have any use for the antiquated, inefficient system of feet and miles. See more »

Star Trek Horror
1 August 2006 | by (New York City) – See all my reviews

Obsession offers a very extraordinary antagonist--a "monster" that's an intelligent gas, made of an element that's not supposed to exist "naturally", and that's able to transform itself as a means of camouflage. Although there are some very broad parallels to this idea in other episodes, including Who Mourns for Adonais?, the material is handled very uniquely here.

We are also presented with an intriguing and unusual exploration of Captain Kirk's psychology, and through that, a bit of Starfleet history. Kirk is the source of the title, Obsession. He harbors deeply buried guilt, stemming from an incident on another ship when he was still a junior officer. His guilt suddenly rises to the surface after encountering this episode's antagonist. Because of this, he becomes obsessed with conquering the "monster", and it affects his judgments seriously enough that his command of the Enterprise is threatened.

As good as it was, the original Star Trek didn't often get close to more gut-level, scary horror material. This episode does, largely because the antagonist is unpredictable, shape shifting and nearly invisible much of the time. It functions as more of a generalized token of a threat to one's life force, made more literal in the way that the "monster" attacks its victims and sustains itself. At times, Obsession's structure and content--including emotional content, almost resemble later horror sci-fi like Alien (1979), which could have easily been influenced by it.

This episode is also notable for some extended, unusual cooperation and agreement between Spock and McCoy.
