TL;DR/DC? The OT of Star Wars had a revelation that shook the movie going world to its core. No other story/film continuity has done so before or since to my reckoning. (Although Star Trek did take a pretty decent swing at it.)
Interested? Read at thine own peril.
As I recall, the initial concept of Star Wars was a simple story of good vs evil. A boy, a girl, and a galaxy at war. An imperiled princess, and a black knight. The galaxy under the rule of a merciless Empire. Keeping it simple is what helped Star Wars win such universal appeal, and put science fiction back on the map, even though Star Wars is space fantasy.
The story matured a bit with Empire Strikes Back. A bit more dimension was given to the characters and their relationships. And a revelation was made that shook the movie going world.
It took some folks going back to the original Star Wars, and listening to certain bits of dialogue to see if this revelation suddenly came from out of nowhere. All one needed do was listen three elements:
Aunt Beru: He's just not a farmer, Owen. He has too much of his father in him.
Uncle Owen: That's what I'm afraid of.
At Ben Kenobi's hovel:
Luke: My father didn't fight in the Clone Wars, he was a navigator on a spice freighter.
Obi-Wan: That's what your uncle told you. He didn't hold with your father's ideals. Thought you should've stayed here and not gotten involved.
Also, watch Ben Kenobi's expression when Luke asks Ben how his father died. There is a brief hesitation....very subtle, but very much there. Then he concocts the story of a "pupil of his". A young Jedi named Darth Vader who turned to evil.
Once I watched those scenes again as a kid, I knew that there could be no other answer. Darth Vader was Luke's father. Uncle Owen's overbearing overprotectiveness of Luke was the first clue. Obi-Wan's brief hesitation was the second. This was confirmed in Return of the Jedi with Yoda's confession, and ghostly Obi-Wan's revision of his own story.
It was all so subtly done that the initial dialogue in Star Wars flew right over moviegoers' heads. This was no accident.
Such events are what shook the moviegoing world at its core. Simplicity, mythological facing, and subtlety.
I'd say it was very praiseworthy, because the only story/movie series I've ever heard that came anywhere close would be the Harry Potter novels/movies.... and then at that, it's a pretty distant closeness... and then at that, it was a minor tremor, not a world rocking revelation of things like Star Wars.
However, Star Trek did take a pretty good swing at it. (And please
note, that I do not say any of this as disparagement towards Star Trek, because I love Trek as well.)
The producers of Star Trek realized that Star Wars was their buy-in to bring Trek back to the visual forefront of sci-fi entertainment. Every company wanted a piece of Star Wars' action.
Universal-- Battlestar Galactica
Walt Disney Co.-- The Black Hole
New World Pictures (minor movie company)-- Battle Beyond the Stars
Paramount-- Star Trek.
Star Trek The Motion Picture was a visual feast, but many felt the story was dull and plodding, the characters were flat and wooden shadows of their past TV selves. ST TMP was a financial success, but a critical flub. It's gotten a lot more love in recent years though.
What Paramount needed was something to truly stand its own ground with Star Wars.... so they had their own trilogy.
Star Trek II: The Wrath of Khan-- Much more exciting than TMP. It had space battles, a menace from its past, and a tragic event. The event generated a lot more buzz in its original premise because of its finality. It generated a
lot of negative feedback, and was changed to be a bit more ambiguous. Oh, there was also that revelation about David Marcus being Kirk's son. (A not so subtle borrowing from TESB that had nowhere near the impact of Darth Vader/Luke Skywalker.)
Star Trek III: The Search for Spock-- Continued on the "Genesis Trilogy". A crew reunited, a fierce Klingon enemy, and two more saddening events. The death of Kirk's son, whom we never really got to know, so the anguish wasn't really there. The destruction of the Enterprise however did more than tremble a few hearts and open a few tear ducts.
Star Trek IV: The Voyage Home-- Pretty much wrapped up the Genesis part of the trilogy with the hearing at the beginning of the movie, and the Spock story was being neatly tied off.
A lot of what sold the Genesis Trilogy was "shock and awe". It hit you over the head with the death and eventual resurrection of Spock, and the destruction of the old Enterprise, and the rise of a new ship.
Star Wars was much more subtle.
But the payoff for both is very appreciable.
