The new wave of body horror flicks posits that the greatest threat to the sanctity of our vital organs is... ourselves. 2010's Splice told the story of a pair of geneticists creating new hybrid animals for use in medical research. Of course, they get greedy and start stirring some human genetic material in there, and things go off the rails. The product of their experimentation is one of the most disquieting body horror monsters ever. Played by the striking Delphine Chanaec, it's just human enough to get our empathy but just alien enough to make us want to kill it with fire. Then there's the whole sex thing.
