Silly, stupid movie - Spoilers
I don't know if this movie is close to the book material and I don't care since James Patterson is a hack. But the movie is just plain stupid from the first minute.
The story solution relies entirely on believing that a young girl victim has MacGyver like intellect to hatch escape techniques along with a maturity to determine adult's motives, and young woman antagonist who is brilliant right up to the point that she leaves a mountain of evidence on her computer including her victim's location.
Both of those circumstances are less believable than the Star Trek universe of technology occurring next month.
Total hogwash. And at the end, when the kidnapped girl INSTANTLY suspects her former protector the young woman, and INSTANTLY accepts the protection of the older detective who SHE'S NEVER MET is stupid beyond anything.
All the way through just a horrid waste of ridiculous fantasy.
