Loved it as a kid (saw it in '83 when i was 10 years old). Through the years I have come to realize that the movie is so much more inferior to Star Wars and Empire. I will never hate the movie simply because it is part III to my beloved Trilogy I grew up with, but it will always be the least watched of the OT for me.
I have to say Jedi is the movie that is most ruined by Lucas changes. 'Jedi Rocks' shows that Lucas has lost touch on what is cool in movies today, and Hayden in the Force Ghost scene shows that Lucas has lost touch into what the damn story is about!
