This is a superb movie. Meryl Streep plays the character of Sister Aloysius to perfection and leaves one with a far greater respect for the old fashioned nuns who ran iron fisted schools with hearts of love (quite a paradox!). Philip Seymour Hoffman plays one of those smooth talking, good preaching, "compassionate" priests who were out to reform the Church while doing great harm to weakest members of their flocks. The conflict and the "doubt" that arises throughout the movie is riveting. This is one of those very rare movies that deserves a "10"
The original movie emerged out of the MAD world of the Soviet-US cold war; this one is coming out of the world of 'global warming' and terrorism, so it may be a bit harder to identify with being on the edge of the precipice (to borrow a line from the script). Also, there is no indication that anything about humankind had changed at the end of the movie other than the promise of perhaps 90% of us dying off and a return to Locke's "state of nature" (hardly an imporvement). Finally, as an Orthodox Christian I would have found it much more intriguing to hear Klaatu say, "the Universe (God in today's pc vocabulary?) wastes no-one" vs "nothing". Once again, Al Gore and the Gaian's pretense that humans are just another species....
