Apparently, George Lucas thinks that The Empire Strikes Back was the worst of all the Star Wars movies. Ironic, then, that it is the one most commonly held up and revered by die-hard fans as being the best of all time. (And, according to “SF Signal”:http://feeds.feedburner.com/~r/Sfsignal/~3/89256649/004779.html, it’s also the one written by a sci-fi author and not directed by Lucas.) It really, _really_ makes me question Lucas’ judgment on quality, now.
(And for the record, I actually thought Jedi was pretty good, it being among my personal favorites.)
Update: Mm, my bad. Looks like Lucas was joking.
