Just came out of it. Casting is on point but otherwise it's just about the least interesting adaptation I could imagine. It's horror as theme park ride, with constantly flying camera, fast cutting and LOUD NOISES substituting for atmosphere and sense of place, and all rough edges from the novel sanded off. Basically competent but utterly predictable, and rushed as hell, like a Harry Potter movie (I don't mean that as a compliment) with scares.
