Our review:
Parents say : Not yet rated
Kids say : Not yet rated

Based on a graphic novel by Kevin Grevioux -- who here takes on directional duties -- this action flick is under no pretensions about what type of movie it is. King of Killers wastes no time providing a hero with a tragic back story -- flawed assassin Garan, played with high-kicking ease by veteran performer Moussi -- and a "winner takes all" scenario that will be instantly familiar to fans of the Saw and Hunger Games franchises. This sets in motion a lengthy procession of set pieces in which various unfortunates are kicked, punched, shot, stabbed, and in one case separated between head and shoulders. The pumping but generic techno score is as familiar as everything else, not least the movie using up its best ideas for novelty deaths early on. Like its embattled cast of characters, the movie makes it across the finish line slightly winded and in worse shape than when it started. Cameos from Stephen Dorff and mixed martial arts ace Georges St-Pierre throw us a couple of famous faces to glimpse at along the way. But both have the right idea and don't outstay their welcome, which is more than can be said for the sequel that's hinted at in the closing stages.
