Revenge of the Sith is a GREAT movie. Of it's genre, it's one of the very best. No polemic required; the packed movie house and the cheering says it all. Vox populi. Buy a bag of popcorn and a giant belly buster of a cola and sit with your kids for a few hours of pure thrills.
Of course, the ultra right will see that differently and applaud its critics. That is expected. Their inability to relax and enjoy the ride is totally in character. That's why they wear ties: it keeps their heads attached when their hearts are trying to gnaw their red necks off.
"So that is how liberty dies: to the sound of thunderous applause."
Well said, Lucas.
