District 9. Not really an overrated movie. And it did have a message. But I just don't care for that kind of film making. It was kind of tough for an old geezer like me to watch.
you truly have to separate the first three (episodes IV, V and VI) from the other thing that George lucas came up with later......
The music
The special effects (totally cuttig edge on its time)
The story which turned totally ugly on episode V
and the underlining message which to me is "things that appear to be right at the moment can turn into a total clusterfuck without being apparent to anyone............."
