You have to make your own decisions for your own kids, but here’s what I went with:
Star Wars
Empire
Jedi
Force Awakens
Last Jedi
We started before Force Awakens came out, so they got to see the sequels in the theater. I consider the current trilogy to be “their” trilogy, but they had to have a schooling in the classics first.
They know of the prequels, but I just said, “They’re not very good” and that was the end of it. The special editions have never been mentioned.
