I have not read the original novel this movie is based on, so I can't say if this movie is better or worse than its source material. But I can judge the movie on its own merits. The movie does have a number of strengths. It looks pretty nice, filmed on location in the Netherlands and Belgium with some good photography. The acting is also pretty good, with a child protagonist that (thank goodness) is not annoying, and the adult actors also doing well. The movie also has some positive messages, ranging from kindness to animals to encouraging people to stick to their dreams and never giving up.
So what goes wrong with the movie to make it not worth a recommendation? Well, to put it bluntly, the movie is quite dull. It's very slow-moving; you have to wait until more than halfway through before some serious problems come up for the characters. And even from that point on, the movie's energy level still remains quite low. I'm certainly not asking for blazing action and suspense that's found in today's hyper-kinetic family films, but I think the story could have been made to be more engaging. Too bad - there are some nice things about this movie, but in the end it's a miss.
