The most intriguing aspect of this story is the question of what the truth is and what actually happened. The "possession"/possession is filmed for TV with all the exaggerations, suggestions and nuances that come with it, which affects Merry's recollection years later as she tells the story to the reporter and works through it in her pseudonymous blog. Incorporating the unreliability of memory was clever and mirrors our own conflicting opinions on what's happening. I really enjoyed the blog posts discussing each episode spliced between the retelling of actual events. And yeah, there's a twist, but overall it fell flat for me. I didn't feel any atmospheric buildup, characters were pretty banal (kid-Merry was insanely annoying for me, but that's beside the point), and I would've liked some introspective passages for each character at various points - for example, give us an insight into the confessional bits. Also, the cover is creepier than the book. Ultimately: meh.
