In "Blood," Joe(Paul Bettany) and Chrissie(Stephen Graham) Fairburn are the sons of a cop, Lenny(Brian Cox), who still shows up at the precinct house from time to time. So, of course it figures they would become police detectives themselves. Their latest case involves the brutal murder of a young girl. They think they have a suspect in Jason Buliegh(Ben Crompton) who certainly seems sleazy enough but they do not have enough evidence to hold him. So, Joe and Chrissie decide to take Jason to the islands in order to have a further chat with him. "Blood" has certain things going for it like a moody atmosphere and a neat use of locations. On the other hand, it is definitely lacking in the story department. So much so, that it solves its central mystery not once but twice before conveniently forgetting about it. Yes, there is a twist but in the long term that does not really change anything. And then there is the miscasting in central roles which undermines any dramatic exploration of the central relationships. What does work is the scene when Lenny is introduced in the foreground, in front of and interrupting his son Joe.
