So that video....?
They say it was their daddy but not their mommy.
This leads you to believe there's a bigger connection and a mystery to solve. Who is the girl in the video? What's the connection with this family/this girl/Emelie? Is this Emilie's motivation for picking this family? How does Emilie have the video?
But nope. No answers. No connection, then? Just a random selection? How did she have the video? Who was this girl the dad was having sex with?
I'd like the movie a lot more if I had some clarity on this video. And if the ending was stronger. A lot of great suspense and mystery built up in the first hour... with a bit of a weak payoff and no answers in the final act.
