A New Hope is not that good of a movie. Yes, the story is strong, but it’s so difficult to enjoy it since the visuals are so outdated and the pacing is extremely slow at times.
Return of the Jedi is also very mediocre. The Tatooine and Endor storylines feel very disconnected, like it’s two movies patched into one film (sort of like Norm of the North: Keys to the Kingdom), and the Endor stuff is just… eh. I’ll give credit to the stuff with Luke, Vader and Palpatine.
