Ever since I first read the book Crusade in Jeans I was hoping they would turn it into a movie. And now they finally did. Dolf Vega is a rather selfish teenager. Because of him a crucial soccer-match is lost. His mum is a scientist and she's working on a time machine. Dolf is seeking revenge for his shame and wants to use the machine to get a chance to get even. But things go wrong and he's stranded in the year 1202! The moment he arrives he's almost killed and saved by some children and a young lady. They take him to the children's crusade on its way to Jerusalem. Soon Dolf uses his modern day wit and knowledge for the good of the poor hungry and sick children. Will he ever get back to his own modern life? This is a great adaption of the book. Not completely faithful but very satisfying. The young leads, in fact, everybody is cast really well. The production looks great although some scenery is obviously computer enhanced. The story is captivating and the running time is just right. The only thing that did not satisfy me personally was the ending which was not like in the book and a bit vague. Highly recommended for children and their ( thirty-something ) parents.
