“IT: Welcome to Derry” was easily my favorite show of 2025. I’ve always been a huge fan of this franchise, from Andy Muschietti’s movies to Stephen King’s original novel, so getting to spend eight episodes digging deeper into the history of Derry and Pennywise was basically horror fan heaven for me.The prequel series takes us back to 1962, decades before the events of “IT,” following a group of children and their families as they uncover the terrifying force that has haunted Derry for generations. And clearly, I wasn’t the only one hooked. When the series debuted on HBO Max in October 2025, it attracted 5.7 million viewers in its first three days, making it the platform’s third-biggest series premiere at the time.After months of waiting, HBO has now officially confirmed that “Welcome to Derry” is coming back for season 2. Even better, we already know it will take us another 27 years into the past, to 1935 during the Great Depression, where the story will centre on the infamous Bradley Gang massacre from King’s novel. And with Derry’s history leaving plenty of room for speculation, I’ve got five theories about where the story could go next.
