Spurting blood from jugular veins! Arrows through necks! Axes in heads! Cute adolescent girls mowed down by machine-gun fire! Decapitations! Grenade in a mouth! Shocking when all this carnage is inflicted on a middle-school class....by classmates. 2000's "Battle Royale" may be an over-the-top exploitation film (...the Japanese are great at these). Or....perhaps this grouchy uncle to "The Hunger Games" is biting social commentary regarding how society is devolving in it's treatment of children. You decide...but for lots of gore, killing, and exploitation...."Battle Royale."
