SPOILER WARNING: The following article contains massive spoilers for the first episode of IT: Welcome To Derry. If you have not yet watched it, proceed at your own risk!
IT: Welcome To Derry is an exciting series for Stephen King fans, as it’s not really a traditional prequel (in that it doesn’t tell a story centered on a particular character with whom we’re already familiar). Instead, what the show is really about is canon expansion: it takes what we already learned from the horror in IT: Chapter One and IT: Chapter Two and builds on it while also taking a step backward in the timeline. The result of this is not only a cool structure, but also many awesome opportunities for fun references and canon ties.
