I can definitely understand that line of thinking. Star Wars was in reality designed as a singular film without any real intention for sequels. And this really was because no one could have predicted it would become the second highest grossing film of all time. You aren’t going to set people up for sequels that wouldn’t come out.
Now I mean I like a ton of SW stuff across all the movies, shows, games, etc. as many know on here but Star Wars is still far and above my favorite film and piece of the whole franchise. I’ve seen it vastly more times than ESB and ROTJ. It’s only one I could fully quote scenes from. Rogue One easily became my second favorite because it played to that original, along with offering some innovative cinematography and some more refined acting performances.
That said, I’m thinking that if any film could be my new favorite, it would be TLJ, simply because of how much I love Rian Johnson’s previous works, and that I do take some liking to the super mystical aspects of Star Wars that have been missing from the films, something that’s sort of the opposite end from what SW and RO are like.
And also yes, glad you haven’t watched the sequels to Jaws or BTTF, they don’t at all compare.
