A scaled green creature rises up from the water. Gills down the sides of his neck pulse, and veins along his body light up in blue as he moves. Human-like in form, he stands tall on two feet. To some, this creature elicits fear and disgust. Others, however, are more curious. Director Guillermo del Toro manages to seamlessly blend fantasy and reality in “The Shape of Water,” which has been nominated for 13 Oscar awards.
