Just watched this movie, rented the DVD. It is a good film, about a very bad thing or perhaps two bad people. I didn't like watching it because of the topics covered and admitedly how well they are covered. I must admit it is good that a 'Hollywood' film has had this effect upon me as it is a rare occurance.
Reminded me (I did not need reminding) of all the very very stupid and selfish games that adults play on each other all the time giving no thought to the children of the family.
As a film I would say this is very good, my favorite moment would be the last thirty seconds. Worth watching.
