“Funhouse” (** out of four) was an underdone horror show about 8 internet celebrities from around the globe (Valter Skarsgard, Khamisa Wilsher, Gigi Saul Guerrero, and others) who compete in an online reality show in which they soon realize they are playing for their very lives and their deaths will soon be broadcast to the entire world. Not the worst of its kind, with some gruesomely imaginative kills and amusing irony, but just a bunch of ideas collected from other and better movies (“The Hunger Games” in particular). By this point- is there really anything left to satirize about social media and the mass commercialism of violence?
