“Smiley Faced Killers” (*1/2 out of four) was a listless melodrama about a young soccer player (Ronen Rubinstein) who believes he is going insane which alienates virtually everyone around him and leads to him eventually unraveling mentally and psychologically. Unpleasant story exploitively deals with mental illness without much depth or interest and winds up a waste of time. A disappointment from director Tim Hunter (“River’s Edge”) and writer Brett Easton Ellis (“American Psycho” and “Less Than Zero”) who have covered similar terrain in other films much more poignantly.
