It’s more than 60%. I, II, III are awful. IV is ok but just a cliche “rescue the princess plot. I was dumbstruck when I saw it for first time at how tired the plot was, I really expected something better for how overhyped the franchise is. V didn’t do much for me but others seem to like it, especially Solo sexually assaulting Leia. I don’t get it. VI is half bad half good. I haven’t seen the new ones but everyone seemed to like VII for the nostalgia but didn’t like VIII much and IX was a mess.
The only reason Star Wars is such a big deal is because George Lucas is an amazing business man and the first movie had some great special effects (and his wife was able to save it in editing). Star Wars is the most overrated thing ever. It’s all marketing.
I find the fandom around Star Wars infinitely more entertaining than the films themselves. The Phantom Edit, Darth Jar Jar, the guys made a whole site to convince themselves they liked Episode I (and everyone who praised it coming out the theatre), the nerds that learn all the alien names from the Cantina, the women who dress up as Princess Leia as a sex slave… Mind blowing.
