The tone of the movie is frightening. The first reason is in the movie their house flooded and there are alligator in the water that try to eat them. The next reason was because at the begin the little boy Alan Parish got sucked into the game. The last reason is because there was a dude shooting at them with an AK.This is why i think the tone of the movie is frightening.
The tone of the book is also frightening. The first reason is because there was a huge python wrapped around the mantle clock. The second reason is because the monkeys raided their kitchen.
