The trailer opens with Vin Diesel's voiceover that I'm almost too embarrassed to type: "Save the planet. What for? Life's simple: Kill or be killed. A survivor's code. My code. It all sounds great until the day you find yourself confronted by a choice -- a choice to make a difference or to walk away and save yourself. I learned something that day. Too bad it was the day I died." Um, okay, Vin. Then we get strains of the Kronos Quartet's amazing Requiem for a Dream music, which is way too good for this trailer, and also overplayed to a point that I've almost started to hate it. The moral of this story seems to be: Vin Diesel is a troubled hero. He's angry, aggressive, tattooed and hot. It's, like, the end of the world or something, but he still has time for some sweet lovin' with a pretty young thing. You know the type? Typical action-movie hero.
