Audio/visual unsynchronized: SPOILER: The mobile phone the couple attempt to use to call the Police after their son's shooting is a Nokia. When switched on, a Nokia start up tone is used. However, the key tone is that of a Motorola (the tone is heard when they press the Call button after 911).
ZOMG. UNNECCESARY NOTICING OF STUPID SHIT IN MOVIES. WHOEVER YOU ARE, DUDE WHO FIGURED THAT OUT, I HOPE YOU DIE A HORRIBLE DEATH.
