I do not get the low ratings. This is a family movie, that indeed completely strays from the plot from the book, but is nevertheless a lot of fun to watch. The actors are great, the kids starring in the movie did a fantastic job, there is a lot of action, jokes and fun all around. I watched it with my three kids, ages from 10 to later teens, and they enjoyed this immensely. I think that all the bad reviews might stem from the PRL nostalgia of the older generation, or from the core fans of the book series. Do not be put off by them and give this movie a try. I would personally rate this as 9, but my kids, who are the real target here, regard this as a sure 10, so 10 it is.
