Average fare. Not enough character build-up for you to be invested in them. Unnecessary family drama in the beginning of the movie and in the monologues in between, adds nothing to the story except drag the movie by 30 minutes.
The special effects are simulated well, but the camera work is poor. Shakes too much and there's too much darkness in several shots, to the point it's not enjoyable.
Would not recommend one to watch it, but it's not terrible either. Passable.
