Bryan Singer fee-fi-fo-fumbles the ball with Jack the Giant Slayer, a lifeless CGI-soaked fantasy adventure that manages to make an invasion by giants seem an entirely pedestrian event. One of those projects that was probably misconceived from the very beginning (how DO you make an epic adventure out of what is essentially a silly fairy tale?), the various ingredients fail to gel into a satisfying whole. A weak script, miscast stars and uneven tone result in a stodgy pudding with too little excitement to sustain its high concept. With any luck this is a brief misstep in the careers of all involved, who are capable of far, far better than this.
