I read the novel, and honestly I'm a bit disappointed with the movie. The spirit of Hector Malot is somewhat missing, and there're a few illogical moments in the movie, like when Vitalis and Remi went to London, where did they get the money to do that? and Mattia, a very important character, is missing. Still, the acting and the soundtrack made it up for the lack of original spirit. Perhaps it's just the book itself is so great that the movie cannot reach to that level of finesse.
