Sigh, the movie was disappointing.
Goes to show one should never judge a movie by its trailer.
Those who have not read the book would be utterly confused, unless he can follow the whole proceedings of the movie attentively and put them all together in nanoseconds.
The story just zips through from one scene to another. Even though I know it is impossible to squeeze a 400 page book into a 2 hour movie or a 3 month long journey into 5 minutes, but moving through the whole motions at such a breakneck speed doesn't do the story any justice.
There were a few things which was changed from the book. Not too drastic a change but I can understand where the producers were coming from to make the movie more manageable and a few less things to explain.
I totally agree with Janvier about the whole daemon-human connection thing being lost in the movie. The scene where Billy Costa (in the book it was a different) was found after the intercision had no impact at all, as his parents and the gyptians didn't even blink an eye for his missing daemon.
If one were to read the reviews from IMDB, it would seem that those who haven't read the book found the movie to be good. Those who had read the book would inevitably say that the book is better, which is true. Movies very seldom can live up to the books, not even the famous boy wizard.
I strongly suggest that viewers go buy the book after watching movie. Or better yet, pay a little more and just buy the book and forget about the movie.
Overall, I would rate the movie 6 out of 10.
