It's the X Games. It's in 3-D. It's in movie theaters. What else do you need to know? If 80 minutes' worth of tribal-tattooed dudes on BMX bikes flipping off ramps floats your boat, go for it. If the names Dave Mirra and Mat Hoffman mean nothing to you, steer clear. Not to be confused with 2002's Ultimate X: The Movie, which ... uh, was not in 3-D. PG.
