Arthur and the Minimoys/Arthur and the Invisibles
This movie is actually based on two books: Arthur and the Minimoys and Arthur and the Forbidden City. Plot-wise, the movie follows the books relatively well. There are changes of course. It is inevitable in a movie for timelines to be shortened, locations to change, that sort of thing. Casting is sort of a mixed bag. Freddy Highmore was a great choice for Arthur, Mia Farrow as Granny not so much. My biggest issue with this movie is actually the pacing. While the books tend to drag a little, the movie races ahead, jumping from scene to scene without pause or reflection. Even the dialogue progresses too quickly. It doesn't reflect the natural flow of a conversation at all. I felt like the movie focused entirely too much on special effects and quips instead of the complex plot and world-building of the novels.
