Generally, I like Harlen Coben's books. I've seen several of his books made into movies. Some are successful; some are not. This one isn't a good movie. At least it is in English without subtitles necessary. Some of the actors did a really good job--the characters of Marty, some of Kierce, some of the main character lady. But the ending!!!! OK, the surprise switcheroo could have been interesting. But the last few minutes were totally unnecessary and rather poor. It made no sense to show that. It wasn't a good conclusion. And the half-brother's storyline was useless. Why?? What did it add?? Sorry, I was very disappointed.
