XXX is not a movie about plot or character. It is a movie about gadgets, girls, explosions, and "golly, did you see that?" They have taken the essence of 14-year-old boy fantasy and put it up on the screen. This is
The Dirty Dozen with one guy playing all twelve parts.
There are some great stunts, especially a snowboard race with an avalanche that would be scarier if it didn't recall the similar scene with Scrat at the beginning of Ice Age. It is too bad that the bad guy is not as interesting as X -- he's just a generic post-communist era guy with an evil plan, a big mouth, a remote control, a girlfriend who is too smart and pretty for him, and a getaway speedboat. But this movie is clearly designed as the first of a series, and it is all about X. Diesel is just the guy for the part, delivering the lines, the kisses, and the action scenes with attitude to spare.
