Very disturbing, violent and lotsa swearing, if that's ok with you then this is a good movie. Paints a very probable road rage scenario initially and then turns in into violence for the sake of violence.
Russel Crow really put everything into the role including his health, dunno if it was a fat suit but he is obese and looked to be on the verge of a heart attack the entire movie.
All the acting was good, cool car crashes, completely unbelievable way he gets away with what he's doing.
My only concern is that somebody is gonna try to take it to a real level, which in this day and age is a distinct possibility.,
