To start off, apparently this site didn't review much material, because though the site does not account for many objectionable actions, they are contained all throughout. Firstly the show has frequent binge drinking, references to drinking and drunkenness, characters who are visibly inebriated, and use of alcohol to "numb" pain. Cigarettes are often used as well. There are also multiple sex scenes in a few episodes, mostly implied, with some implied nudity and shots of both men and women in revealing undergarments. Much of the violence is VERY graphic, with people being blown up, shot repeatedly at close range, individuals bleeding out in a very emotional manner, and once a father being blown up in front of his son who watches in horror. Also to tackle is the fact that no one is as they seem, and without giving spoilers I will say that by the end of the run many of the "good guys" end up betraying, and even killing their friends. Also up for disturbing content are a few very graphic medical procedures, including one in which the patient screams to the doctors to allow him to die. In the end though friendship, loyalty, quick witted intellect, and a strong commitment to a just cause do prevail, though at a very high cost, and through many difficult decisions. The show is a great action packed joy ride, but only for mature individuals who can handle the extreme violence, betrayal, and emotion presented.
