Newsweek has a new article they posted after having seen Episode III. Here's a clip of their thoughts:

This is the most savage and despairing of the "Star Wars" movies. The surviving Jedi knights are forced into exile, and the Empire consolidates its evil power. This glimpse of intergalactic hell inspires moments of epic grandeur that haven't been felt since "The Empire Strikes Back." It's hard not to feel that Lucas's engagement with this story has a contemporary urgency, as line after pointed line invites us to see a parallel with today's wartime climate. As the Senate cedes power to Palpatine under the guise of intergalactic security, Natalie Portman's Princess Padme exclaims bitterly, "So this is how liberty dies?to thunderous applause."

Twenty-eight years after "Star Wars," the curtain finally falls. Lucas started by remixing myriad old Hollywood formulas into a hyperspace hybrid that felt new. Now, at the end, his own formula has inevitably become old-fashioned itself. For all the technological changes Lucas has embraced, his wide-eyed, childlike approach to storytelling?cute robots, scary villains, selfless heroics, fortune-cookie wisdom and wild roller-coaster rides through space?has remained the same. You can argue whether it's for better or worse. What you can't argue with is that he's stayed true to his vision, and that that vision has changed the cultural landscape irrevocably.
