In our modern era, the Library of Congress has created the National Film Registry, which has films from 1891 to 1999. Sadly, none of the ST films is on that registry, but two Star Wars films, A New Hope and The Empire Strikes Back are on that list.

And genius needs to be restrained. Look at what Spielberg did with Jaws. I don't think the movie would've been so great if everything had gone according to plan.
