I liked parts of Ep. 6 as well, and watching it again the Ewoks do not compare in annoyance to Jar Jar.
Jar Jar was evil, and even I can see the horrific racial stereotype that good, liberal Mr. Lucas was perpetuating. Of course, I do believe at the time that Rolling Stone had made Jar Jar their cover boy, saying he was the coolest new screen presence since Chewbacca, or something.
