My friend Arne posted a ranking of Star Wars movies on his blog. Below you can find mine.
- A New Hope
- The Empire Strikes Back
- The Last Jedi
- Rogue One
- Return of the Jedi
- The Force Awakens
(I've never seen the Ewok and Droid movies, so can't really place them in the list.)
I do wonder what those other three movies on his list are. There are rumors about prequels, but as far as I know, they don't exist?
