It: Welcome to Derry premieres this weekend, taking viewers back to 1962 to witness a new group of kids tormented by an ancient, fear-fueled clown. Much of the original It centers on kids and teens facing terrifying danger, so its no surprise the series follows suit. However, HBOs Welcome to Derry pushes the scares even further than Andy Muschiettis recent It films, and the series sets this brutal new tone faster than audiences may expect.
