Don't be put off by the IMDb score, or any negative reviews, this movie is a more than worthy successor to Death Race 2, and has earned its place in the franchise.
Lots of subtle humour, stylish action and surprisingly memorably characters, all combined with sufficiently varied and suitably over-the-top set pieces make this feel more like a cinema release than a direct-to-video offering.
Sure, the plot gets a bit silly at times, and there are clichés and stereotypes liberally scattered throughout, but I still found the new setting, the new (if often short-lived) characters and the tidy wrapping up of the story arc to be effective and entertaining.
Dougray Scott shines as the enthusiastic antagonist, relative unknown Jeremy Crutchley provides a great Russell Crowe-esque caricature, and even Luke Goss manages to steal some good moments.
All of the actors look like they're having lots of fun, and I too thoroughly enjoyed the movie. Dig it up and give it a go. Watch all three movies back to back for the full experience!
