I hate this kind of movie, but all the reviewers go on and on about the “completely predictable” 'twist" ending. so SPOIL ME!! 
You really do get to hear De Niro say…
Come out, come out wherever you are.
well, first there are these people that are hiding from a seeker. then near the end of the movie the seeker finds the hiders, yells “I found you!!” And the roles are reversed so the former hiders are now seeking the hinding seeker.
