Storyline

When the planet Sarpeidon is about to be destroyed by its star Beta Niobe becoming a supernova, Kirk, Spock and McCoy beam down and find it evacuated except for its librarian, Mr. Atoz, tending with his replicas a collection of unusual discs, which play the planet's history and (to their surprise) allow their users to travel into the past trough the atavachron, a time machine, into the periods each was studying on disc, but they travel unprepared. McCoy and Spock find themselves locked in a frozen ice age 5,000 years ago, where Spock reverts to the barbaric age of the Vulcans, hence touchy and intensely attracted to the political prisoner Zarabeth, who enjoys getting company but tells them return is impossible. Kirk arrives in a Cromwellian period, where he's arrested and suspected of witchcraft, but realizes the magistrate must be a time traveler like him, and learns not being prepared at molecular level he can return through the time portal, and in fact must do so and contact Spock ...

Goofs

When in the Ice Age period, Spock starts regressing at the level of his ancestors five thousand years earlier. However, McCoy does not. Behaviorally speaking, humans have remained relatively unchanged over the past 5,000 years, despite our technological advances. The Vulcan people were on the brink of oblivion not because of what they could do technologically, but who they were emotionally. Humans now are similar to humans at the beginning of the Bronze Age, regardless of our technological advances. See more »

Quotes

Captain James T. Kirk: You're a very agile man, Mr. Atoz. Just how many of you are there? We came as soon as we knew what was happening.
Mr. Spock: Forgive me, sir. It is my fault. I must have miscalculated. Our readings indicated that there was no one here at all.
Mr. Atoz: Of course I know. Everyone on this planet was warned of the coming nova long ago. They followed instructions and are now safe. And you had better do the same.

An Interesting Idea Stretched Thin
25 July 2016 | by See all my reviews

Kirk, Spock and McCoy beam down to a planet to warn its inhabitants of an impending disaster, only to find themselves trapped in the planet's past.

"All Our Yesterdays" has echoes of "City on the Edge of Forever" but takes the concept in a completely different direction. Instead of traveling into the past and trying to figure out how not to alter it and never mind how they get back, here they have to figure out how to get back and never mind how much they alter it. The point is, it's a twist on one of the most popular episodes of the series, so the elements are there for a great episode.

Unfortunately, those elements never really come together. Kirk finds himself imprisoned in a Renaissance period and must find a way to escape; Spock and McCoy are trapped in an arctic wilderness and must find shelter. Neither story is particularly compelling, barely filling its time on screen. We also have a frame story set in a "library" where the time travel is managed. That part never feels like anything more than filler. It doesn't help that there's such a short time frame in which the story plays out. This is something that would have worked better over days, not hours.

The best part of the episode is Spock's narrative, as he finds himself losing control of his emotions and falling in love with a woman trapped in the past with him. But that part of the episode doesn't quite make sense. We're told that the effects of time travel will be deadly, but Spock is the only one who shows any adverse effects at all -- and McCoy's explanation of the effects he suffers are nothing like what are described by others. (Speaking of McCoy, his accusations against Zarabeth seem unfounded, as far as anyone actually knows.) And the crew has traveled into the past before; why is it so deadly this time? And why doesn't Spock's phaser work?

Ultimately what we are left with is a feeling of incompleteness. The away team members travel into the past, spend some time in an enclosed area talking to the locals, then return to their own time...and some scenes in a "library" fill out the time. For all that's at stake, nothing seems very urgent or grand. "All Our Yesterdays" is probably one of the better third-season episodes, but overall it's middle-of- the-road at best.
