The novelization lets us peek into the mind of the titans in a way the movies don’t.
I like the idea that King Kong just didn’t care enough to get involved in all this.
It helps us understand their motivations, or in this case, lack of motivation, and that’s only a benefit to the larger story.
One of the difficulties in making these giant monster movies and letting us see them from the human perspective is that we can’t really understand the emotions and the motivation of the creatures themselves.
