Be warned, "The Day the Earth Stood Still" starts slowly and modestly and is mired in a minefield of movie cliches. But give "Day" a few moments to warm up. There are some spectacular moments, and some innovative moments, even if a lot of it was imagined for the first time in 1951.
It is interesting to see the number of movies coming out now with a more and more serious message. People -- collectively -- will have to change. The message is becoming more radical in the movie zeitgeist, which makes this a timely and appropriate flick and a worthy addition to this particular theme. Interestingly, and uniquely, this flick cites exactly this sentiment, where (sitting in McDonalds) one being says to another:
"They sense their own demise but don't know what to do about it." Or words to that effect.
