I enjoyed this movie immensely! It was wonderfully suspenseful. It pulled me right along and kept me guessing. The acting was superb, especially those children. My only complaint was that there was too much whispering. I had to keep adjusting my volume so as not to miss anything. Probably a good reason for watching it in a theater.
Fifteen minutes before the end, I had guessed what was happening. I thought I should have guessed sooner, but was glad I didn't. That would have taken out some of the fun!
