No real takeaways here; it's mainly a revenge story centered around terrorist acts.
Blood and gore. Guns and shooting. Many people are shot in a massacre, with blood spurts. Body parts are cut/sliced. Dead, gory body with throat sliced and fingers severed. A young boy sees gory pictures of a crime scene. A character falls to his death, is shown splatted on the sidewalk. Terrorist bombers. Face plunged in boiling water. Fighting, punching.
Brief full-frontal female nudity. Couple in bed together; the man leaves the bed, and the naked woman follows, embraces and kisses him. Characters are said to have been in an extramarital affair.
Several uses of "f--k," a use of "a--hole," a use of "oh, Christ."
Alcoholic beverages on view. Characters discuss former problems with alcohol and attending AA meetings.
