With a generic title like Never Back Downwhat, was Action-Related Content already taken?theres no way this unlikely hybrid of The Karate Kid and Fight Club could set your hopes lower without scraping the Mariana Trench. But if you dig the eye-of-the-tiger genrewhich rarely rewards anyone who cant pick nits between Kickboxer 4: The Aggressor and Kickboxer 5: The Redemptionyoull recognize director Jeff Wadlows brawny teen melodrama as a modest surprise: better acted than needed, better made than expected. Sean Faris, the evident result of that top-secret Tom Cruise/Ben Affleck/Adam Sandler gene-splicing experiment, plays the troubled new kid at an Orlando high school who gets a YouTube-broadcast beatdown from an upper-crust underground fighter (Cam Gigandet). With the help of a Senegalese Mr. Miyagi (Djimon Hounsou) and the bullys regretful girlfriend (Amber Heard), the kid gets his esteem back and loses the chip on his shoulderbut the bully still wants another shot. Chris Hautys script hits every predictable plot point, but the engaging cast looks like a portfolio of future starsespecially Faris, a buff beefcake whos self-effacing enough to make a credible underdogand the bone-jarring fight scenes rock as hard as theyre shot and cut. It may be just OK nowbut trust me, when it airs at 2 a.m. on Spike between male-enhancement ads, its gonna look like The Magnificent freakin Ambersons. — Jim Ridley
