Having read the book, this movie fell short of my expectations. In making the movie I know poetic license comes into play BUT changing areas can detract from the story line. For example, in the movie Luna Lovegood finds Harry on the train after Malfoy casted his freezing spell BUT in the book it was Tonks who releases him. This would seem to be a minor difference but to we diehard book enthusiasts it clearly stands out as a movie booboo. Overall, this movie falls short of doing this book segment justice.
