Nightmare Fuel / Die Hard with a Vengeance

• The way Katya gleefully tears the helpless security guard apart with her dagger, and would not even let his mangled corpse fall to the floor until Simon stops her.
  • And the way she smiles while she kills her boyfriend by shooting him to death.
• John and Zeus dispatch one of Simon's henchmen on the freighter when a snapped cable tears the mook literally in half (on screen). They are later seen dragging away the two halves of his body, fortunately with somewhat of a Gory Discretion Shot.
• The very idea of a bomb being planted in a school which your child may be attending. Realistic consequences kick in when people across New York hear about the threat, and immediately drop everything they’re doing to get their kids out of school.
• The scene of the shoe store blowing up in the beginning was pretty scary, and takes on a new dimension of Harsher in Hindsight in light of the Boston Marathon bombings of 2013.
• As does the entire plot—terrorist attacks across New York City on a late summer day. At one point when John and Zeus are on foot, running to Thompson Square Park, the Twin Towers are prominent in the background.
