I can grasp your feelings with the dialog. I remember feeling embarrassed at the cinema when watching phantom and clones. And I really tried to like those movies. In the end I skipped Sith and watched it with a six pack of beer on TV some years later.

I was soo hesistant when watching TFA at the cinema. And that movie succeeded at what I considered impossible at that time: I felt home in the Star Wars universe again. I think part of that might have been Kasdan’s dialogues in it. But there was the magic again that I remembered seeing th OT as a kid.
