OK, I've read some pretty harsh comments on this movie. Now, let me state this: This is not a multi-million dollar movie. This movie was not shot using stunt drivers, stand-ins, and using special effects to create the illusion of speed. This movie was made using real street racers from California and their real cars. Nothing was built just for the film and none of the races were staged either.
That being said, I say this is a great movie because of all of the statements above. The warning on the front cover warns all viewers of the realism included. That should have been a waring to all who gave this movie a poor rating that, "Hey, this movie may not be Hollywood fake like the fast and the furious was." This movie was created by someone who wanted to depict what real street racing was all about. It follows the lives of street racers and is based more on "Documentary with a storyline". That is, it shows what really happens on a day-to-day basis in the lives of us underground racers.
Long review short: If you want a real story with real excitement, this is your movie. If you are a street racing fan and want to see how we live on a day by day basis then watch this film. If you are looking for cheesy Hollywood knock offs with million dollar camera effects and retarded stories about robbing trucks, look elsewhere.
