"Parasyte: The Grey," the ambitiously re-imagined series by star director Yeon Sang-ho, is a run-of-the-mill monster horror show that fails to capture the charm and essence of the original manga. The 6-part Netflix original series follows the story of Jung Soo-in (Jung So-nee) as she is partially turned into a monster after an alien species called the Parasytes invade Earth. The series is set in the univers.
