This may raise some eyebrows, but just go with it for now. If you plan on introducing someone to Star Wars for the first time, try showing the movies in this order:

Star Wars
The Empire Strikes Back
Return of the Jedi
Attack of the Clones
Revenge of the Sith
The Phantom Menace
Solo: A Star Wars Story
Rogue One: A Star Wars Story
The Force Awakens
The Last Jedi
The Rise of Skywalker

Why this order? Skipping The Phantom Menace until later... you're doing them a favor.
I wouldn't skip Menace entirely because we might need it to fully appreciate this last movie coming up!

I just went full nerd here. You're welcome.
