Yeah and like... in the tunnel he could HEAR something coming up behind him! THAT was creepy! I think Jack experienced the animals too, when he was doing some work outside, and every time he turned to look at them they were getting closer... and closer... and closer. He chalked it up to him hallucinating, but man! Creepy stuff! And yeah, using the snow falling off them as you said, good stuff!
Yeah it's hard to find someone who's read the book these days. XD So yeah, glad you read it too!

I like too how the book kind of explained some back story to some scenes you see in the movie but were never explained. Like when Wendy saw Roger, the guy in the dog costume in that room, and you're just like what the...? Cause you don't KNOW who that is... or the woman in room 237 (different room number in the book). The book actually explains pretty in depth who Roger and that woman are, and in particular, why Roger is dressed like a dog. XD
