I think the screenwriters did a great job showing us the important aspects of a long novel on the big screen. Unlike other reviewers, I was not bothered by the liberties taken with some pieces of the story (maybe that's because I haven't re-read the book in years... and thus ignorance was bliss!) The effects were amazing and Harry and his brood were wonderful. It's been great to see all the characters grow up. All in all, a thoroughly enjoyable (although heart-wrenching) experience.
