As an adult, I find myself hooked to the very movie. The darkness is definitely meant for the adults I must say. I will not suggest any adolescent to watch without any parental guidance.
But i must say the engagement is good, plot and storyline is good . The only thing I find that the film can be improved is in the length and the details of the entire settings.
I don't understand why film raters are rating it so low despite being such a great movie. I am a movie enthusiast but there is seldom one which really catch my attention through the entire film (I go for smoke breaks if the movie doesn't attract me in a way this film does) . This film made me kept still on my seats till the very end.
