The Haunting of Hill House

Obviously, this book has been out for some years and been adapted several times, so I won't bore anyone with details you already know. I mainly wanted to touch on two points:
1) As good as the story was, I could have been longer. Details were iffy at times. The movies try to expand the back story a bit, but not always effectively. Can't blame them for trying. I liked the ending, but I'm not entirely sure that the novel really gave the reader enough of a reason why everything turned out the way it did.
2) No one I've seen really talks about this, but this book is freakin' hilarious. I found myself laughing out loud quite a few times.
