A father (Casey Affleck) and young Rag (Anna Pniowsky) are living in the woods and trying to avoid strangers. Flashbacks reveal a global troubled time with his wife (Elisabeth Moss). This is a premise that would be better served by revealing it much later. This reveal happens too early and in the cliché way of a newspaper headline. One would expect him to find allies, most likely another single father with a boy. One would definitely expect him to be armed. Quite frankly, this should start with Affleck and another guy with the two kids on the run from armed military forces. The other guy sacrifices himself for the group to escape and the movie can be about Affleck with two kids. It would start the film with a bang and it would be more reasonable for the premise. Also, Rag's reveal needs to be a big thing. The movie doesn't know how to place the reveals. The sex talk scene needs some work. It could be played for laughs but like all sex talk with your dad, it gets awkward and not funny. The idea is funnier than the execution. It needs to do something different like filming only Rag's face as the talk happens. This is a premise movie that needs a few tweaks.
