"^You shouldn't take any of it too literally because it's fiction. Everything about it is subject to revision or reinterpretation."
Well, this forum and its participants speaks volumes that this isn't just about a "TV show". From a writer's point of view "everything about it is subject to revision or reinterpretation" could be a convenient excuse for not doing accurate research which, IMHO, is the cause of many contradictions in the fictional
universe of Star Trek and to a much lesser degree because of changed premises of the original producers / creators.
The only excuse for me would be a darn good story. One of the best Star Trek stories I ever read was Peter David's Q-Squared.
It wasn't great because of his accurate research but that helped a lot to really make it credible and enjoyable.
