Problems
- The ship travels almost 30 light years in a matter of days. Maybe a couple weeks. This would require a speed of a lot faster than warp 5!
- Nora says the Horizon is low on deuterium... surely she meant dilithium.

Factoids
- There was a time, before Starfleet was chartered, when Archer considered serving on a cargo ship.
- According to Trip, Zefram Cochrane designed the cargo ships like the J class cargo ships himself.
- This episode establishes that Enterprise has visited 22 inhabited planets and traveled 150 light years in 18 months.

Remarkable Scenes
- Travis hanging out at the sweet spot.
- Travis: "Starfleet really ought to think about putting families on starships." Reed: "You must be joking!" Mayweather : "No one would ever get homesick." Reed : "Yes... well they'd better post a psychologist on board. Because I'd need one if my parents were roaming the corridors."
- Archer joining Travis at the sweet spot.
- Archer telling Travis about the letter of recommendation he got from Travis' father.
- The Horizon being attacked.
- T'Pol's reaction to the movie.
- The Horizon battling the aliens.

My Review
Ent: Horizon is a good episode, worthy of the series. Unfortunately, it's nearly identical to Ent: Fortunate Son. Some of the nuances of the rehash could have been avoided. For one, I would have preferred Travis' father had not died and instead of a sibling conflict we could see a father son conflict. That would have been more interesting in my opinion. Most importantly this episode features yet another stubborn leader who refuses help and yet another alien attack on a cargo ship. This is beginning to strain credibility. Are all cargo ship captains stubborn luddites who are under constant attack by pirates? The episode's basic premise could have been made into something better if the writers had decided to write a bit more original story. Instead, we're shown a pretty blatant rehash that only a year ago was a pretty nicely original idea.
