If you are looking realism then don't watch this movie or most movies for a matter of fact. Movies are for entertainment. Go watch documentaries if you want realism. But if your just looking for a thrilling movie to keep you on the edge of your seat, then this movie is for you. It has good jump scares and less dialogues to keep the action going. It's a breath of new air since most movies has been actions with guns and cars and stuff the like.
