A lot of critics, I don't think. quite knew what to make of this film: it is hyper over the top. is incredibly dark, yet also steals elements from the video game Mario Kart, and tries to send a message about the private prisons at the same time. It's an interesting matchup, one of which the medium of movies was, I'd argue. tailor made for.. There are some not so great elements at play too including a rather annoying shaky cam, but I could overlook them easily enough.
