I was really disappointed with this movie. The preview is amazing and I couldn't wait to see it. I hunted it down ever since it came out. But it's not what I was hoping for. It's a little slow on some parts. And the ending doesn't resolve anything. It doesn't tell how or why all that was happening. But the beginning scene is very good and got me in the mood. And throughout, the dramatic irony and suspense builds up and up. Some scenes are actually pretty scary. This movie will leave you hoping to be around some light.
