I don't entirely disagree.Limitations are a beautiful thing for art. That's why the PT feels so underwhelming. I'm sure many would argue the ST suffers this too, but I think the PT is more so.
Personally, I am of the opinion that Star Wars should have just been Star Wars. No ESB, no ROTJ, no franchise. I would give it all up for just SW.
The real problem with the new films is that damn mystery box. Just because there was a big reveal in empire, Disney and JJ thinks that SW is ABOUT the mystery.
To me it's about space battles, hallway battles, the spectacle of war, funny and relatable characters, and people coming together. That beats mystery shit every time. It might have deepened the mythology in Empire, but it all; feels unearned and superficial in the new trilogy.
