Consider this humanity's final warning.

"My name is General Zod. I have journeyed across an ocean of stars to reach you. Your world has sheltered one of my citizens. He will look like you, but he is not one of you. To those of you who know his location, the fate of your planet rests in your hands. To Kal-El, I say this: surrender in 24 hours, or watch this world suffer the consequences."

So goes the ominous transmission from Michael Shannon's villainous Kryptonian in the exhilarating new trailer for "Man of Steel," by far the most action-packed yet and one that puts Zod and his lethal army (including Antje Traue's steely-eyed Faora) center stage. Just try not to get goose-bumps during that final climactic swell of Hans Zimmer's score. Just try.

My grade for the trailer: A+. After watching it, rate it for yourself at top left.
