I'm not one to leave a negative review normally (or any review for that matter), but what a snoozer. I've had more exciting naps. Great cast, but one of the most boring "horror" movies. I was unswayed but the sub 6 audience score after reading a few of the decent metacritic reviews. Boy, was I surprised. Very atmospheric, but little substance. An hour in I was checking my watch wondering when something interesting would happen, and continued to wonder until the closing credits.
Very disappointed.
