In my opinion, aside from not being as good as the book, it was in general a pretty bad movie. The characters were sort of cliche stereotypes (but Mark Wahlberg did a great job). What the heck was all the loopy doop "heaven" stuff that went on way too long?! That wasn't in the book! I was surprised it was bad since the director ROCKED for Lord of the Rings.
One massive flaw I noticed, was, remember when she snuck into the house and found the journal? And you saw her walk by the ten ton safe with her sister's body in it on the floor in the basement? Then she narrowly escaped with the journal, and the murderer had to INSTANTLY flee authorities. Fast forward to him "dumping the safe which is so heavy he needed help to push it to the landfill from a truck"
HELLO? Are we supposed to think he really quick ran up the stairs with that safe when he fled? But anyway. It was disturbing too. I think any mom will be disturbed watching abductions take place. I read the book before I had kids, and watched the movie recently. Hated it. I hate when movies are badly done, but pull your heartstrings just because the subject is disturbing. But for the record, I also thought the book fell apart half way through, and was only well written in the first half.
