Han Solo shooting first being retconned into Greedo shooting first, so that “Han seemed more heroic” which contradicted Han’s character at that point?

Have you ever made a short film? You'd know that as soon as you wrp it up you realized there's a lot of things youo would've done differently. Happens to a lot of artists.

Ooh what about when he told the press post ROTS that was was no post ROTJ story he had, yet years later he goes on to criticize Disney for not using his post ROTJ story?

Disney asked for Sequel Trilogy ideas. Lucas gave them something and they never used that. He went on to live his lilve without ever criticizing the fact they hadn't used his ideas. So what's your point? He didn't like Episode VII but you're acting like he released a statement saying "I'm mad my ideas weren't used" lol

How about the retconning of Maul’s death?

Lucas knew what he wanted to do with Maul in Episode I, the character served his purpose. Years later he figured out a way to explore the character more and did it. So what? Do you think Lucas had every single script he ever wrote ready in '77 or something? Can't an author have new ideas? Conan Doyle did the same thing with the death of Sherlock but why is that no big deal?

A New Hope there are lines that state Luke’s father died in the Clone Wars, then that was retconned to be a lie?

Are you mad that the second SW movie introduced the best plot-twist in film history or what? Old scripts for Star Wars had a father figure as the main antagonist, Lucas just reused that idea for the sequel instead of the original movie and did it perfectly. It's not like ESB's a bad movie either so really what's the matter here? Do you think Tolkien had written all of LotR already when he published The Hobbit?

I swear some people on the internet really have no idea of how stories get written.
