Unfortunately, viewers must endure a large number of obscenities and strong profanity, particularly from a jealous police detective (Paul Rodriguez) who frequently belittles McCaleb’s work. While gunshots are often fired, the violence is rarely graphic, although a frequently shown videotape of a gunshot to the head seems slightly gory. And a wounded man is held under bloody water until dead. One scene indicates a sexual encounter between Graciella and Terry, which is crudely referenced later. Sadly, the frequent foul language seriously taints “Blood Work.”
