**Review:**  
“All Our Yesterdays” is a standout near the end 
of *Star Trek: The Original Series*, rich with 
science fiction intrigue, character exploration, 
and a poignant emotional core — especially 
for Mr. Spock.

The Enterprise arrives at the planet 
**Sarpeidon**, whose sun is about to go 
nova. To their surprise, the population has 
vanished — seemingly disappeared into the past 
via a time travel machine called the **Atavachron**, 
operated by the mysterious librarian **Mr. Atoz**. 
When Kirk, Spock, and McCoy investigate, they’re 
each accidentally hurled into different 
historical periods.

Kirk lands in a sword-and-candle era that 
resembles 17th-century Europe, while Spock 
and McCoy find themselves trapped in a harsh 
ice age — and this is where the story becomes 
truly compelling. There, they meet **Zarabeth**, 
a tragic and beautiful exile. As the cold 
presses in, Spock begins to regress to his 
primitive Vulcan roots — emotionally raw, 
impulsive, and eventually… tender. He develops 
an unexpected (and touching) bond with Zarabeth, 
awakening feelings he normally suppresses.

The idea that traveling back through 
the Atavachron physically alters you to adapt to 
that era is a fascinating sci-fi twist, raising 
the stakes for our heroes to escape 
before the changes become permanent. Meanwhile, 
Kirk must outwit a paranoid local justice system
in his own time-travel zone.

The story plays with the themes of **time, loss, 
loneliness**, and **the irreversible pull 
of the past**. The quiet tragedy of Zarabeth, 
doomed to live alone in a frozen wasteland, echoes 
long after the episode ends — especially with 
Spock forced to leave her behind, restoring his 
stoic persona even as we know he has been 
forever changed.

**Strengths:**
- Deep character exploration, 
especially for Spock.
- Clever time travel mechanics 
with real narrative consequences.
- Atmospheric setting, 
especially the icy past.
- Melancholic and emotionally 
resonant without being melodramatic.

**Weaknesses:**
- A few minor pacing issues, 
especially in Kirk’s subplot.
- Atoz’s character, while fun, 
feels a bit repetitive after a while.

**Verdict:**  
A haunting, emotional, and inventive episode
that shows *Star Trek* at its most 
introspective. “All Our Yesterdays” 
gracefully blends science fiction with personal 
tragedy and philosophical reflection. Spock’s 
emotional unraveling — and rebuilding — makes 
this one of the most memorable episodes 
of the series.

**Score: 87/100**  
(*Poignant time-travel tale with emotional 
weight and classic Trek heart.*)
