We understand allegory, metaphor, and that sometimes the representation of a thing isn't the thing itself. Thus we can read a sci-fi story and understand that the important part isn't how many souls the evil empire trapped in an intergalactic prison, but rather the nobility of those who oppose such an evil force.
Fiction--including science fiction and fantasy--offers us a glimpse at human nature that we may never otherwise experience in our day-to-day life, and that's enjoyable. Science fiction and fantasy can do that all the more clearly by removing historical biases. No side in reality is universally good or evil. The USA did some horrifying things in WWII, and the South wasn't completely composed of brutal psychopaths who thought the height of entertainment was flaying blacks alive. Make the opposition a demonic force, and you can make the good/evil element infinitely more clear. Or, you can go the other way--there's no question that the Nazis needed to be destroyed, so a story calling into question the validity of war that focuses on WWII isn't going to go well. Make it an interplanetary empire, though, and suddenly the subtleties of cultures and the validity of full-scale warfare can be extremely easy to portray. Once you eliminate the cultural baggage that comes along with nonfiction, the field's far more open and allows a good author to make a much more nuanced presentation of extremely complex themes.

I do kind of know what you mean though, as a biochemist by trade I cannot watch any movie/series that shows 'real' use of those techniques. Movies like Outbreak or series like CSI I cannot help but shouting in my head 'It doesnt WORK that way!!!'.
I've been thrown out of two viewings of movies for this. When my family watched "The Day After Tomorrow" my brother-in-law and I started proving, with references, just how dumb the ideas were. When we got out the encyclopedias we were locked out of the room the TV was in. The second time was watching "The Core" with a bunch of geologists. A few of us started drawing diagrams and equations showing the stupidity of the movie, and when we erased the board for the third time we were told to leave by people with pointy-ended rock hammers.
But strangely enough once it becomes fictional enough that it should be clear to anyone that it IS fiction this switches off. Star trek medicine or Fringe I have no problem watching. Odd but true.
It's the Uncanny Valley. If it's similar enough to reality that you can reasonably expect the laws of reality to hold true, deviations are extremely apparent. However, if it's so different that you can't assume the laws of reality hold true, you can easily accept the laws of the story's reality as long as they are consistent. Which honestly is another reason I enjoy sci-fi and fantasy: the good versions show me a world that's completely different from my own, which frankly is fun. It's the same concept as vacationing in a different country.
