Either

-How sloppy the trilogy is in structure, pacing, and character building
-How uncreative the trilogy is in bringing back planet destroying weapons twice, bringing back the emperor, and having another twist related to the main character’s family
-The weird lack of romance (despite plenty of sexual tension)
-How there’s never any restraint or subtlety.
-How the Force is basically just video game-ish magic instead of a Shinto style connection to a spiritual world
-How they lean on the OT for emotional resonance rather than getting it from their own plot lines and characters.
-The squandered opportunity of it all

I think so much of it is a reflection of how the majority of Hollywood has really forgotten how to make quality mass entertainment.
