This movie - rated PG-13 and released on January 30, 2009, was very good, in my opinion. I must preface this with the fact that I "love" scary, suspensful, thriller-type movies. This one wasn't too scary - but very suspensful and had an ending I just wasn't expecting...another huge plus for me.
Basically a film of unknown stars - I only recognized David Strathairn, who played the father - it was well acted. It wasn't cheesy like many "scary" movies tend to be. They managed to keep me waiting to see what would happen and rooting for the underdog.
