20 Things You Didn't Know About Star Trek V: The Final Frontier
3. Dating The Film Is A Bit Of A Challenge
The TOS-era movies, from the Wrath of Khan until the Final Frontier, all seemingly take place in 2286. The Final Frontier in fact follows the Voyage Home by a matter of weeks, which itself was only three months after the end of Search for Spock. All four films then are crammed into a very short space of time.
The Romulan Ambassador to Nimbus III, Dar, states that the planet was established twenty years prior as the first great attempt by the Romulan, Klingon, and Federation governments to foster a peace treaty. This would seem to fall in line with the events of Errand of Mercy, where the Organians effectively forced a stalemate in the quadrant.
However.
The third season of the Next Generation premiered not long after the film's release. In its first episode, Evolution, Data states that there hasn't been a ship-wide systems failure in seventy-nine years. As this is most likely a tongue-in-cheek reference to the Final Frontier, that would place the events of the film in 2287.
Though the dating issue is the least of the film's problems, it just seems to be one more thing that Star Trek V: The Final Frontier has standing between it and film perfection.
