Why settle for an A in history, when you can get an X? That’s just one of the questionable lessons imparted in this feature-length 3-D commercial for the X Games. Here’s another: Some people view gravity like others do evolution, i.e., just a theory. Say what? It’s true that the athletes—among them Shaun White, Travis Pastrana and Bob Burnquist—are all freakishly fearless, awe-inspiring and yes, often airborne. But such dime-store philosophy, coupled with the running commentary from the Games’ heinously Spicoli-esque announcers (“Dude, that was the hardest slam we’ve ever seen!”), ruins an otherwise gripping, in-your-face experience.
