Before I summarize the movie, I have to say that I was very pleasantly surprised. The imdb rating is totally off, not to mention that there was a very smart twist at the end that completely took me by surprise and I loved the casting! And in addition to that it has a great soundtrack. I'm not 100% sure what the people who gave it 5,4 stars were expecting, but for me it was 9/10. And I'll tell you why in a minute. (Spoilers up ahead!)
That said, I was actually amazed by how the story evolved. It completely surprised me. There was still 40 minutes to go when Carrie Anne died and I had no idea of what was going to happen. Turns out that Ryan's parents where junkies who were just too high to do anything about their daughter's death and since it was Ryan playing with her, he is blamed for it.
Beware that it is a psycho-thriller and it will stay with you for a while and even if the scary bits aren't that strong, the whole concept of Ryan's story is very hard on the viewer. But do check it out, you won't be disappointed!
Until the next item on the thriller list!
