This movie somewhat reminded me of "A.I. Artificial Intelligence", a movie that started out like a drama and in the end felt like a fairy tale story. "Before I Wake" has the feel of a horror movie at times, but turns into, albeit a scary one, a fairy tale. The good: The actors did a fine job, especially the two leads. A well written story and the fantasy effects looks good. The bad: The monster did not look very scary, but I guess there is a reason for that in the story. The movie is promoted as a horror, I guess that will leave some viewers disappointed. This is not The Conjuring or Saw. This is a fantasy with some scary elements.
