My Best Friend's Exorcism

I remember finishing the book in a day. It was an original, well-paced and fun read that I just could not put down until every page was turned. Sometimes that does not always translate to the screen, but I still found the film to be quite entertaining. The book had some pretty heavy, dark scenes and I was surprised that the movie did as well. I figured it would be presented more as a comedy than a horror film, playing more to mainstream viewers. However, there were some genuinely creepy aspects to the mostly dramatic script. It's such an original concept that it may be too unusual for those who haven't read the novel.
