The Watcher 2022 may have some differences from the true story. In the show, the visual and auditory elements create a more intense atmosphere than what the real family might have actually experienced. The show might also simplify or combine some aspects of the real events to make it more coherent for the viewers. For instance, the way the family investigates in the show could be different from what really happened. Also, the relationships between the characters in the show might be more dramatized to add to the suspense, whereas in the real story they were probably more ordinary day - to - day relationships.
One difference could be the portrayal of the neighbors. In the show, the neighbors might be presented in a more suspicious or involved way compared to the real story. Also, the timeline in the show could be adjusted to fit the narrative better, while in the true story it was more of a real - time sequence of events that unfolded. And the characters' backstories in the show might be more fleshed out than in the real events just to make the story more engaging.
Well, in the show there might be some added drama for entertainment purposes. In the true story, the details might have been more straightforward. For example, the show might exaggerate the reactions of the characters a bit.
