There are movies that you watch, enjoy and soon forget about. This movie lingers at the back of your head and never goes away. This movie sets a standard for cop/murder mystery genre. A must watch before you die.
To be honest don't I mean don't ever watch a movie after judging it by rating. This movie it worth it. Just take your time, grab a comfy chair and enjoy it. The acting, story, plot and cinematography is just excellent. By far this is and should be Mel Gibson's best movie of the decade.
