- Harsher in Hindsight:
- "Unification" ends on a hopeful note that the young of Romulus will eventually replace their warmongering elders and embrace their relationship with Vulcan on far more friendly terms. Neither will happen; the Romulus of this universe is canonically vaporized by a supernova in Star Trek (2009), giving Nero the impetus to go back in time and screw around with the alternate universe of the Abrams films. And then, Star Trek: Picard reveals that Picard was so heartbroken by this that he'd left Starfleet.
- On the other hand, the Star Trek Online verse shows that D'Tan and the other members of the underground eventually achieve their dreams in the form of the Romulan Republic.
- An out-of-universe example: The Romulans' invasion plan, since Russia used basically the same plan to take Crimea in 2014.
- Idiot Plot:
- Yes, 2,000 Romulan soldiers should have absolutely no problem handling the billions of Vulcan geniuses who are just as physically tough as they are and know their home planet, its technological infrastructure, and its resources a lot better than they do! Even worse in hindsight, as Tuvok would later reveal that there is a "Vulcan Institute for Defensive Arts," clearly indicating that their pacifism does not extend to passively allowing themselves to get beaten up by just anyone who tries to roll them for their lunch money. Though, as pointed out above, the Russian invasion and annexation of Ukraine followed the same principle.
- And on the subject of stupidity, we might as well say it again: Sela, you idiot! What the hell were you thinking, leaving the heroes alone in a room with a computer? Especially after she actively recognized the ship Data commanded during "Redemption," shortly before he defeated her, and now knows he's right here in front of her.
- Values Resonance: Nowadays, it isn't hard to compare Spock with politicians like Jeremy Corbyn in the UK or Bernie Sanders in the US, as elder statesmen who strike a chord with younger activists hoping to make their world better. Spock's last lines to Picard still resonate thanks to the populist wave of The New '10s.Spock: An inexorable evolution toward a Vulcan philosophy has already begun. Like the first Vulcans, these people are struggling to a new enlightenment, and it may take decades or even centuries for them to reach it, but they will reach it... and I must help.
