Just finished the novel!

And just have to say sleepless nights ahead. I loved the characters and found Regan's  slow descent into possession more effective than presented in the movie. Also loved Blatty's writing style, it was immediately gripping and kept me enveloped till the end. Just out of curiosity what did others prefer, book or films. Personally i found the film better, that is the original cut of the film, it was more focused than the TVYNS. But the book was far scarier. What do you guys think?
