Most of the time I only watch the OT, but when I want to watch more, I prefer to just watch the movies where Luke is alive:
- Revenge of the Sith
- A New Hope
- The Empire Strikes Back
- Return of the Jedi
- The Force Awakens
- The Last Jedi
It starts with Luke’s conception and ends with Luke’s death, and you don’t have to watch any of the worst movies in the series.
