The other day I was engaged in a discussion, not an argument mind you, on Twitter concerning Star Trek: Strange New Worlds and its violation of Star Trek’s established canon.
I myself am not bothered by violation of ‘canon’ if the result are more interesting character, deep stories, and compelling plotlines.

It is interesting to remember that Star Trek was not designed to have a rigid history with a lore and a canon well-defined. The original series is a product of 1960’s television and, in that day and age, television worked quite differently than it does today at the end of the first quarter of the 21st century. A program was deemed successful if it ran for at least 5 seasons of 20 plus episodes. That produced enough episodes that the series could be ‘stripped,’ run on weekday afternoons in random order. Season five episodes might precede season one episodes so there were no continuing storylines, one episode rarely affected the events in another.
Star Trek, and here I am referring to the original run, the original cast feature films, presented a contradictory and inconsistent ‘canon’ for its future history. Here are some examples.
In The Conscience of the King when McCoy asks Spock to share a drink with him, Spock comments his father’s race was spared the dubious benefits of alcohol to which McCoy replied, “Now I know why you were conquered.” Who conquered Vulcan? No one, this bit of history was discarded.
Pon Farr the mysterious and secretive collection of rituals and biological drives surrounding Vulcan reproduction. Which is it: the thing that ‘no outworlder may know, save for those few who have been involved’ or something Saavik can just casually explain to David Marcus? Additionally with this aspect of Vulcan biology is it something that Spock hoped he would be spared as he said in Amok Time or is it a predictable cycle of every seven years as mentioned in The Cloud Minders and again in Star Trek III: The Search for Spock?
In Space Seed it is established that in the late 20th century a cadre of scientists employing eugenics bred a number of humans with superior abilities creating dictators that sparked the Eugenics War. Eugenics is directed and controlled breeding in human to produce desired traits. In Star Trek II: The Wrath of Khan Chekov explains to his captain that Khan was the product of later 20th century ‘genetic engineering.’ Eugenics, which is breeding for traits, and genetic engineering, which is gene alteration for traits is not the same thing, however advances in science and the public’s understanding of science made the genetic engineering a much more likely scenario, so ‘canon’ changed to fit public perception.
Here’s a biggie. Is it Federation policy to leave planets and cultures to adhere to their own destinies without coercion or as in A Taste of Armageddon or do they have standing general orders for the genocide that any ship’s captain can employ?
My point with these examples is not to ridicule or mock the original series, which I adore, but to demonstrate that a rigid lore or canon has never been an essential element of Star Trek. Strange New Worlds does break accepted ‘canon’, but it does that to give us wonderfully complex and interesting characters and stories so in my book it’s a plus not a minus.
