you can't understand that people like your movie as it was originally created

George Lucas has said in the past that he had bigger plans for the original film(s), but the technology to pull it off didn't exist yet. So he had to make do with what effects he could. He even invented many film effects for the original trilogy, creating his own visual effects studio to pull it off.

In the '90s, he realized CG technology had advanced enough that he could finally fill in the gaps that he couldn't do back in the '70s, and so he released the Special Edition trilogy, which he considered the final and complete masterpiece.

Of course, a lot of people had experienced 2 decades of the original Star Wars trilogy by that point, so adding changes now seemed like inappropriately extending what was already considered a masterpiece.

George Lucas was never satisfied with his films anyway. He kept changing the story, even as they were filming, and it was purely by accident that they ended up being a massive hit. (Which is probably why his prequel trilogy was so hated by fans) I remember reading once that his original plot starred Luke Starkiller, and Leia was supposed to be General Organa and not related to Luke. Also, Luke was originally supposed to fall to the dark side and become the new villain, replacing Darth Vader. Mark Hamill was excited about that twist, until it was changed for a happier ending. He would later go on to play villains in other films, being famously known as the voice of Joker from Batman The Animated Series.

Also, I watched a documentary on VHS back in the early '90s where George Lucas laid out his plan for a 9-movie series. The first trilogy would be about the crumbling of the Galactic Republic, then the second trilogy would be about rebel forces fighting against the new Empire, then the final trilogy would be about rebuilding the Galactic Republic.

But George Lucas thought it would be boring watching 3 whole films about a government slowly collapsing, so he decided to jump into the meat of the conflict and start with the middle trilogy. It was a wild success, even if the plot kept changing as he was filming, and so when he got to the prequel trilogy, he decided to make it about one of the biggest characters from his original trilogy - Vader. Which changed the focus of the prequel films and made them less boring than just a series about space politics, but not nearly as interesting as his original trilogy.

Star Wars fans are a pretty contentious bunch, and the hate for the prequel series caused George Lucas to give up his dream of making 9 films. He eventually sold the franchise to Disney, who immediately started up their own sequel trilogy, plus a ton of spinoff TV series. And it's been pretty strange since then. Episode 7 was basically a modern remake of episode 4, to draw back the fans of the original trilogy. Then Rian Johnson was given the reins for Episode 8, and he hated seeing the same cast of characters in every Star Wars film, so he tried to branch out away from familiar faces. It didn't go well, so Episode 9 shoe-horned in as many familiar characters and stories as it could, to win back fans. The whiplash between films made for a pretty awful and disjointed series.

Personally, I'm on board with the idea that the original trilogy (in it's unedited state) is the ONLY Star Wars series. The rest, I just consider to be non-canon fan films. There's so much that could've been done to add onto the original series. And even the official book series (before Disney marked them as non-canon) had great additions to the plot. But then we got a prequel series about the biggest badass in the galaxy... and it turns out he's just a whiny brat who's manipulated into being a bad guy. Then the sequel series was all over the place. And the spinoff TV shows have been hit-or-miss. So yeah, I consider them all non-canon, including George's Special Edition. And I look forward to seeing the original unedited trilogy in 4K one day.
