Riveting until the very end. spoilers

The moment they discover that she's fine and everything, the film just ends. This should have sent the movie into another trajectory, perhaps involving the daughter being used as bait in order to lure the two parents into a dodgy situation in which they both disappear themselves, or have it not be the daughter after all. The film really ran out of steam at the end. Plus, Harry's realization that he doesn't know the women in his life as much as he thought isn't played for very much. And I totally would have smacked the living *beep* out of the daughter after finding her frolicking with a bunch of kids after sending the parents through absolute hell. Too bad because the film really had potential.
