^Actually, that would be Star Trek.
You didn't need to have seen "The City on the Edge of Forever" to enjoy "Trouble with Tribbles" when ST first aired. You didn't need to know any backstory to follow the original episodes.
That's only because there hadn't been much backstory in those days. Now we have a 50 year old franchise backing up the new movies. If people want to see a scifi movie with no backstory at all, then they should go watch another movie. What's the point in using the name "Star Trek" and the names of the original characters if you ignore everything that came before? I know ... milking the cow, but Star Trek has such a rich backstory that it would be plain stupid not to make use of it.
