Supernanny (2005)

The four Nitti boys are at war with each other and their Mom. Darren (10), Matthew (8), Devin (6) and Jared (5) are so violent that they leave serious welts and scars -- the oldest son has hit, kicked, punched, spit and head-butted his mother, Lisa. Darren admits that he likes hitting because it "takes out his anger." Lisa and her boyfriend, John, have been together for two years, but Lisa doesn't know how to manage her children without resorting to anger or threats to call John, who has a lion's roar that intimidates the boys. The violence between the children heats up in the car, and Lisa and John often can't get more than two blocks from home without having to pull over to manage the chaos. Dinnertime can go into an hour of overtime, as Matthew refuses to eat, and when the younger kids refuse to go to bed, there's no rest for these weary parents.
