Yeah, this is a particular case. I like most of his books and hardly ever feel there's something exaggerated or anything like that. I think, for example, books like Gerald's Game, The Shining, Pet Sematary, they all have that good pace. Especially the short stories like The Man in the Black Suit. It felt so right for me to stop reading on the mouse's death scene. Then when I continued reading I felt like... aaah, no... a little too improbable.
But just as you said, readers have different perceptions when it comes to when the story climaxes.
I was hoping there would be someone who would share my opinion, though. I wonder why the guys that made the movie didn't put that scene too. Hahaha.
(Most people prefer a happy ending)
