My opinions aren’t that unusual, but here they are.

The Phantom Menace: Taking the submarine into Naboo’s core, it was completely unnecessary to the story.
Attack of the Clones: The romantic subplot, enough said.
Revenge of the Sith: Yoda’s fight with Sheev, it was his fight with Dooku turned up to 11.
Solo: L3’s shenanigans, it’s hard to know if we’re supposed to take her seriously or not.
Rogue One: No one scene really bugs me, but the whole first and second act was a bit too slow.
A New Hope: The sandcrawler scene could be shortened a bit, maybe. Nothing outside of SE crap really sticks out to me.
The Empire Strikes Back: Maybe the space slug trying to eat the Falcoln. Again, nothing really bothers me.
Return of the Jedi: The Ewoks, they should have been Wookiees like the original script said.
The Force Awakens: The rathtar scene. The CGI was Prequel level tbh.
The Last Jedi: The Canto Bight side quest, it felt so forced in.
