Revenge/payback are strong themes. Also, terrorists must be destroyed, and crazy science experiments sometimes work.
Tons of graphic violence throughout. Some of the intent is to demonstrate that the criminal character has no emotions (regret, remorse, guilt, etc.), but it's no less cringe-inducing. Guns and shooting, blood spatters. Murder with a metal hook to the neck. Oral electric cattle-prod torture. Punching, bashing, beatings (some via objevcts like axes, lamp bases, and even a cooler). Car crashes with projectiles. Explosions. Missile strikes a plane. Gory crime-scene photos. Gory brain surgery, with bleeding. Gory leg wound, with stitching, dressing, etc. Tranquilizer darts. Yelling. A woman is duct-taped to bed. Small girl kidnapped.
A man strokes a woman's clothed backside with his finger. Brief flashbacks of a married couple touching each other in an intimate way.
Several uses of "f--k," plus "motherf----r," "s--t," a--hole," "ass."
