Starring the likes of Naomi Watts and Bobby Cannavale, Season 1 of The Watcher earned a middling 56% Tomatometer average on Rotten Tomatoes, but it was still a smash hit on the Netflix service. Loosely based on a 2018 article by Reeves Wiedeman for New York magazine's website The Cut, The Watcher follows a married couple who are terrifyingly stalked by way of letters after moving into a new house. Netflix's The Watcher is headed back to the streamer for a Season 2, but what can fans expect for this second outing of the fan-favorite thriller?
