The other two Death Race movies had satisfying plots. This movie had what could have been a satisfying plot, but somehow it fell short. It just wasn’t really particularly clear what was happening or why, so it was hard to care about the characters and events. Moreover, the dialog was amazingly boring. Take away the drama, and it’s just cars and blood and death. Yuck.
The premise is that the moneymaking prison death race management company gets forcibly bought out by a first class jerk, who tells star driver Frankenstein that he in fact cannot win his freedom from prison by winning a fifth race as promised and that instead he is obliged to travel the world to compete and lose to attract fans across the globe.
