'Righteous Kill' remains a mystery to me. You're asking to yourself the question 'How come with such solid actors, Jon Avnet achieves to ruin the movie?'. You see, that's the problem. He focus so much on the Deniro/Pacino duet that he totally forgets the movie. What may have been a promising idea, is totally ruined by the director.
The movie has an interesting plot, but I don't know why I still feel that there are many flaws in it, many holes that burry the film, due to an ignorant error by the director.
However, it wasn't all that bad. Overall, the acting was good and that tag line 'Most people respect the badge. Everybody respects the gun' really is quite something...but wasted. It's a passable 101 minutes popcorn thriller, that isn't bad but it isn't good also.
