A pair of non-corporeal aliens observe the Enterprise crew as they face a crisis. Though they do not want to interfere, they want to be as close to the action as possible... and so they migrate around the ship, possessing different members of the crew with the best vantage points for scientific observation.
This episode is almost a throwback to the sort of self-contained science fiction parable that was classic Star Trek's bread and butter. The only "shout out to the fans" that connects this to Trek history is a blink-and-you'll-miss-it mention that these alien visitors are Organians, the powerful aliens who enforced a peace treaty of sorts between the Federation and the Klingons. It doesn't feel like we're dumping out the Star Trek toy box to play.
No, it's the actors who get to play in this episode. At some point in the hour, every one of the show's seven regular cast members gets to play one of the two aliens. Not only do they get to cut loose and play a new character, they're thrown the challenge of making that character seem consistent across multiple different actors, as the aliens hop bodies.
It's possible that the writers did most of the heavy lifting there. The script was written by Judith and Garfield Reeves-Stevens, the Trek novelists turned show writers I've mentioned previously. The two "observer" characters are sharply drawn with their own personalities and motivations, and are easy to track as they pass from actor to actor.
It's a clever enough story, and entertaining... and yet watching it actually makes me feel sorry for the actors. Reed and Mayweather haven't really had anything good to do on the show in ages. So while I'm glad that Dominic Keating and Anthony Montgomery finally get to headline an episode, it's a shame that we don't learn anything at all about their characters. Hoshi Sato hasn't figured meaningfully into a story all season; now we actually learn a few new details of her back story... but only in the context where she expects to die. (I feel like the Star Trek: Discovery writers saw this and thought it was a good approach they should run with for a while.)
It's more enjoyable to take a step back and appreciate this episode as a sort of inversion of Star Trek. So many episodes of the franchise turn on our heroes butting up against the Prime Directive of non-interference with alien cultures. Here, an alien culture has the exact same policy, and the consequences harm our heroes. The shoe is on the other foot, in a cheeky way. And the moral summation of the episode dances dangerously close to repudiating the Prime Directive, noting the importance of compassion in considering what is moral and just.
Other observations:
- When they don't actually have to show a movie the characters talk about, they aren't limited to old films in the Paramount archives. (Hence, the reference to The Andromeda Strain here.)
- Trip and Hoshi seem to become closer friends from their trial here. I wish the show had been able to make more use of that in the future.
This episode kind of works better for me if you imagine it as a one-off of some anthology series. In the context of Star Trek: Enterprise, it's still decent, but foregrounds the way the series doesn't seem to care enough about its characters. I give "Observer Effect" a B.
