When David shows up at the Peterson’s house claiming to be their dead son’s army buddy, the family immediately takes him in and accepts his story. But who is he really and what does he want?
As David assumes the role of the dead son, each family member takes a liking to him in their own way, but the daughter Anna begins to suspect something is wrong and makes a call to the army to inquire about David.
The first 2/3 of the movie is a nice slow burn of building tension. David is not such a bad guy and really seems to be helping the family cope with their grief. However, there is a sinister side to David that keeps the viewer on their toes. Once the switch flips, the third act kicks into overdrive.
Dan Stevens is great as David. He is charming, stoic, and downright creepy in subtle ways. He’s the focal point that really keeps the character ominous.
My only gripe is that there were some unanswered questions that left it open-ended. I don’t necessarily consider this a bad thing, because what makes the David character so unsettling is how little you really know about him.
