Death Race (2008) offered some mindless guilty pleasure. Death Race 2 (2010) offered a direct-to-video prequel that established the background. Death Race 3: Inferno (Blu-ray release 2013-1-23) attempts to inject new elements into this story, primarily by moving the race track to a desert. Having no new element that improves the action sequences, plus the cinematography and editing makes it less exciting than before, and it’s less clear who is driving which car. If the previous movies are mindless, this one makes much less sense with the details, and I think it is not entirely consistent with the previous ones.
