To those of you put off by some of these reviews on here in regards to the movie being dull... If you don't have children, have a child then watch it again... If you do have children and thought this movie is dull, you either didn't get the point of being a parent, or you're as bad at parenting as these two!
This film is more about the struggles one protecting their own than an actual horror film in my opinion... Best watched with a decent sound system or proper headphones, the sound track is great!
9/10 would scream at the TV to save your son again
Edit: seriously watch this with the sound turned right up and you'll get what I mean about the soundtrack being amazing.
