The OT was a collection of kids' movies that had enough adult appeal to become smash hits. The first Reeves Superman movie and the first Iron Movie were similar in this regard. That's why everyone loves C-3PO and Chewie. But at the end of the day, their #1 purpose was to sell toys.
The PT was a trilogy of the sort of kids' movies that adults can only barely tolerate, but they still succeeded at selling toys and winning over the kiddos. Just about anyone who warmly remembers The Phantom Menace was a child when it came out.
The ST was a trilogy of modern, woke movies made by people who hate the IP, hate the fans, and even hate the original actors, and are little more than a vehicle for the director and producer to rub your nose in how much they despise you and feel entitled to your money. They didn't care what kids wanted, which is why they killed Star Wars completely.
