Really? An experiment? About kidnapping children??
When I read the write up for this and then watched the video, I was infuriated.
It plays into the worst types of myths and stereotyping and scare tactics designed to...I'm not sure what it's designed to do. Terrify parents? Make them think that children are at significant risk of being taken in public, in broad daylight, with adults there who have been "alerted" to the situation by the child? By a kidnapper who persists in his attempts with adults there with telephones?
Has it ever happened? Under the circumstances portrayed in this "experiment?" I sincerely doubt it.
The dedication of the film sets the stage for the reaction the filmmakers hope to elicit: "...the candle that burns for all the angels who have been kidnapped and 'disappeared.' " It would have been nice if they had given a number, or an estimate of a number, but the number of those who are truly kidnapped by strangers and just "disappear" would be so tiny that it would leave the viewer wondering what the hyperbole was all about.
As a piece of fear-mongering, this "experiment" gets an A-; it could have been better acted.
But in the categories of usefulness, realism, and anything even bordering on good taste--it's an F.
