Be non-violent -- or I'll kill you.
God, I just fuggin' hated Klaatu from the moment he opened his mouth. Every smug, condescending word made me want to punch him more. And when he got to his solution, I just knew it was coming, because that's the kind of movie this is, I could tell. Other threads on here have posted on what a horrible message, what a balls-out terrifying solution Klaatu's solution is, so I don't feel the need to explain it. If I was an Earthling in this movie, my immediate course of action would be to start searching for a way to kill the robots before our all-powerful android overlords come down to destroy us all if we misbehaved.
And I want to believe that maybe the filmmakers realized this, realized what a true horror Klaatu is. But I really doubt it. Every scene, with the petty and stupid humans daring to disagree and have conflict, and distrust the alien invader, is set up to make them look like idiots. The only people who aren't made to look grubby and disgusting are the woman and the professor sucking up to Michael Rennie. Then there are the Jesus parallels, and his final scene, where he smiles benevolently upon society and the woman looks up beatifically at him. This movie is so stupid. If it brings up interesting questions, it does so entirely by accident.
