In the near future, crime has been eradicated in the United States—except for 12 hours every year, when bloody hell breaks loose. That day, known as the "Purge," is a no-holds-barred bloodfest. The haves lock themselves into their fortified McMansions, while the have-nots get beaten to pulps in dank alleyways. If it all sounds a little fraught and maybe a touch heavy-handed, I'm not going to spend too much time contradicting you. But it's also a suspenseful, twisty home-invasion flick that's gory and sick and allegorical, blanketed in physical darkness, with a tinge of Bret Easton Ellis-esque American psychopathy for good measure. by Courtney Ferguson
