Have you ever read a book/watched a movie like this (details inside)

The story first starts slowly. Everything is peaceful, maybe a bit boring. Everyone is happy, untroubled. The story’s pace is a bit slow. It gives you the impression that this is a light-hearted story, suitable for everyone, and there will surely be a happy ending.

But then the story slowly builds the tension. It can start with a death, a disappearance, anything unsettling that doesn’t seem to fit the story’s atmosphere. Things just get worse and worse, to the point that the story’s atmosphere changes drastically and the whole story becomes depressing and disturbing. In the end you realize that the story’s peaceful opening is just a lie, the true tone of the story is depressing.
