Well done film that was tense all the way through. My only issue is the change to the ending from the book. Otherwise a good film.

Very good drama. Less is more. Visuals very effective. Short and sweet.

I consider the movie more of a thriller than a horror movie which is good as I was hoping not to see much gore. Enjoyed the premise and I continue to enjoy the M. Knight films as he continues to make them very interesting.

It was ok
