Bloodline is a Dexter-like movie, about a psychopath killing people that he thinks deserve it by their previous bad actions. It's not of the same quality as the series Dexter, but that's difficult as that show had it all, suspense, twists and great characters. Bloodline has some suspense though, and that's a positive thing in this story. The acting wasn't bad either, and there's a twist to it. For a movie about a serial killer it's not a bad one.
