This movie, rented on the urging of Mrs. Salad, is a run-of-the-mill psychological thriller, redeemed somewhat by Dakota Fanning, who does an outstanding job of playing a Creepy Little Girl role.
Robert DeNiro is (of course) good too, although the script pretty much calls for him to one-note his Concerned Father performance through most of the movie.
It's a mediocre script, though, with people showing up who might as well have "Red Herring" buttons pinned to their shirts. Even at 100 minutes (according to the IMDB), it seems to be too long. The DVD includes 4 alternate endings, but none of them are noticeably better. Not recommended for viewing by small children or cats.
