It: Welcome to Derry closes its first season with an eight-episode arc that reimagines Pennywise’s origin in 1962 and connects the creature’s terror to Cold War anxieties, racial violence and the civil rights struggle.Jason Fuchs and Andy Muschietti say the season uses explicit Stephen King homages and original set pieces, including a winged mutant baby and a Carrie-like school assembly scene, to argue that the real monsters in Derry are often human cruelty and systemic racism.Andy Muschietti denied fan theories linking the finale’s fog to The Mist, explaining that the fog follows the show’s internal mythology tied to the Deadlights and an asteroid incident shown earlier, while showrunner Brad Caleb Kane said a true crossover would require a Todash Darkness portal.
