Sean Faris and Djimon Hounsou in Never Back DownNEVER BACK DOWN

Watching the so-silly-it's-almost-fun mixed-martial-arts melodrama Never Back Down, I felt instantly transported to the summer of 1984, when my friends and I saw The Karate Kid the first time around. Fight Club was still 15 years away, so we weren't yet treated to this film's bone-crunchingly "kinetic" violence, nor to the sight of shirtless brawlers pummeling each other with their pants buttoned 12 inches below their navels. (Nor, for that matter, to topless teenage lesbians making out in a jacuzzi.) But Never Back Down is still pretty much Karate Kid redux, and the experience of watching it felt like time-travel for another reason: The movie's high-schooler lead is played by Tom Cruise.
