I think a lot of people, because it was so long ago, don't realize that both Empire and Jedi split the fan base at the time they were released. We just didn't have social media, instant reaction, and conspiratorial
YouTube videos to push a negative message to the masses. Some people hated Empire because it was too slow with way too much talking and not enough action, it was too much of a departure from the first film, they split the characters up on different quests instead of keeping them all together, it had fairly dark themes, and ended on a sad note. Jedi to some felt too light and they hated the Ewoks, or felt it was too much of a movie meant for kids.
