This movie is just plain sad. In addition to mediocre acting, the special effects were just as bad. In one scene you could plainly see the safety wire connected to the motorcycle. Bad diologue and senseless nudity made the film even worse. The plot drug and the resolution could have been solved a little sooner than it did. They came up with a lame chase scene with an airplane cruising on the ground after a motorcycle. Maybe that was a last ditch effort to make the movie a little bit more exciting. The only slightly interesting character was played by LL Cool J. His on camera presence is always rather captivating to me. It also carried him through a poorly written character. Since most of the movie took place on the track, there was more of the game than I could really put up with. Avoid it.

I ordered two of these for my kids. The pump for the rocket is made so you have to hold it while pumping but there is no good way to hold it securely while pumping. There is a trigger to lock in the rocket while pumping but the trigger is in the way of holding the pump and is unsafe because a simple bump makes the rocket launch accidentally. The piston in the pump is so cheap that it bends when you push it in. The end cap on the pump chamber is not properly secured to the pump. I tried the pumps that came with both rockets. The rocket's highest flight was about 10 feet becuase the pumps were so lame.
