Being as fair as I can the acting in this show isn't great but that may well be due to the cartoonish stereotypes of the characters. Main character Detective Cross is the quintisential tough guy, emotionless and confidently walks into a bikie club house without backup and come out ontop and unscathed. Other main character Detective Tully is sleeping her way through the Gold Coast if there is anybody on the coast she hasn't slept with we're yet to meet them. As supporting cast we have a want to be bimbo and a horny incompetent kid.
Still the plots are generally decent and in these days of over formulastic story lines that makes the show worth a look.
