This movie is by far the least like the book. If you have read the book, it's proably best that you DO NOT see this movie. The director/writers have taken out entire story lines (Fleur and Bill, Rufus Scrimjeour, etc..) and added their own (a fight in the fields beside the burrow and the burrow catches on fire--WHAT??). The entire last chapter of the book is missing from the movie!! On the other hand, if you haven't read the book, there is NO WAY you'd be able to follow the story lines that were left in this movie because without all the appropriate sub-stories, the movie just jumps around.
Bottom line: stick to the books-they're always better!
