Seems by having the same director for OOTP, THBP, and both installments of TDH, he has taken a bit of liberty with the story lines for the books knowing that he has 4 movies to put everything back together and finish the series. Things have been omitted, moved around, and changed to the point where fans of the books will be left scratching their heads. Non-readers will enjoy the movie, however, as it is chock full of special effects, humor, and love stories along with everything else expected from a Harry Potter movie.
