Query: Ruthless, underhanded, for real, !...

Denzel is amazing in this movie, watch this movie twice, the first time to catch the storyline and the 2nd time to actually rate the acting, and Denzel Washington is oscar material in this movie. This movie shows you that the good cops have reasons to turn bad and unfortunately some of them do. They get bigger than life on the streets, because they have the badge, but they also get too caught up in the money and power that they eventually will fall. They bring protege's along and show them corrupt ways and if the rookie isn't careful and remember why they joined the force or the team, they will end up corrupt or dead. This movie was real and the acting was totally outstanding. A must see, and if you are a Denzel Washington fan, you will not even realize that this Denzel the good guy or the lover. How many of our finest in blue or under cover are corrupt?... makes you wonder, watch the movie.
