I have written another review here so I won't go into the details of what a great film I thought this was. There's just one thing that I think needs to be metioned here, so that non-Dutch viewers will see the film as it was intended, rather than comment negatively because they were under the false impression it was aimed at adult audiences.
This is a dramatization of a CHILDREN'S novel. A very well-known and well-loved Dutch children's novel in fact, based on the author's (Jan Terlouw) own childhood experiences during the devastating final "Winter of Hunger" (before the northern part of The Netherlands was finally liberated in May 1945). But still, a children's novel, and therefore aimed at an audience of about 9-15 year-olds. In The Netherlands, this film was released as such, as a film for children. Hence the "lack" of gory action scenes or realisticly savage brutality by the hands of the occupiers that some viewers have mentioned in their comments. It was never intended for adult audiences. Maybe this knowledge will set this film in a different light for non-Dutch viewers.
I hope it does, because I loved it, as I loved the book when I was a child growing up in The Netherlands. But keep in mind, this is a story told from the perspective of a child, written for children. Don't let that fact deter you in any way though, you'll miss a solid little gem of a film!
