2. Children of Men
I thought director Alfonso Cuarón's film of P.D. James' futuristic political-fable novel was good when it opened in 2006. After repeated viewings, I know Children of Men is indisputably great. A hypnotic Clive Owen starred as a resistance leader pinning his hopes on the last pregnant woman on Earth. Is it possible to capture the terrible absence of a world without children? Cuarón did it. No movie this decade was more redolent of sorrowful beauty and exhilarating action. You don't just watch the car ambush scene (pure camera wizardry) — you live inside it. That's Cuarón's magic: He makes you believe.
