The Irish Independent criticized Berg for filming children in Ireland without their knowledge.

The film was very well received by critics, earning a 100 percent ‘fresh’ review from RottenTomatoes.com. As of July 2009, the film ranks 6th on Rotten Tomatoes’ list of the best reviewed movies of all time.

After the documentary, which contains highly contraversial movie claims, was shown on Dutch national TV in April 2010, members of a parish in Schiedam recognized O’Grady as an active volunteer in the parish until January 2010. His background was unknown to the parishioners. Apart from that he was active in the Netherlands as an organizer of children’s parties.
