Biggest issues with the sequels?

We all know that the original movie is the best and that the sequels have a lot of problems. What’s the worst one though?

Like, are we supposed to believe that Darth Vader went from merely Tarkin’s henchman to the Emperor’s apprentice? Or, that “Darth” is a title when it’s clearly Vader’s first name!

Changing the order around to make the original the 4th! Luke and Leigh are siblings?!?!? (Though that makes the kiss in the first sequel cool af).

But the worst is that they totally eliminated the “Darth Vader versus Anakin Skywalker” angle and totally ruined the chance for Luke to kill Darth Vader. The sequels totally nerfed the coolest bad guy ever!
