“DNA 2: Bloodline” (*1/2 out of four) was a flatlining action melodrama about a conflicted young man (Winston Brightharp) on the street who’s trying to go straight but gets lured back in and swallowed up by drugs and fast cash which seal his doom. Amateurish collection of cliches and street stereotypes which needed a transfusion of fresh ideas and plot points. Strictly for those who thought the original was robbed at Oscar time but even they’ll likely be bored.
