Just finished watching most of the movie- I saved the final race for tomorrow when I'll be more awake. The movie is a great historical depiction of MX as it follows the 1975 500cc class season down to the final race in which 6 guys have the chance to take the title. If you want an action packed Nitro Circus type movie you will be very disappointed but if you like to see old school racing with a lot of background on both racers and motocross you will like it.
Really follows the On Any Sunday style of filming.
