This is a very interesting movie even though the name of movie is misleading because the earth does not stand still in the movie. I was a little disappointed in that. It is a science fiction movie that is about an alien coming to earth from another planet. He is sent to destroy human kind because he felt like it humans were killing the planet and it was needed to save earth. In the end he is persuaded not to destroy man kind and that humans will fix their mistakes themselves. It is worth watching and it has a political point to it that man kind might be killing the planet and something drastic might need to be done even though I don't think that it needs to be as drastic as aliens coming to earth and killing us off.
