I have to give Rowling credit: she really understands how to structure the books so you can't put them down. Just as you reach the end of a chapter (and, therefore, a logical breakpoint), she sucks you right into the next one.I re-read the series to compare the books to the movies. I think I like the books better than the movies, especially this one. She did an excellent job of tying up the loose ends. The movie had a lot of questionable subjects: like when Harry is using the Resurrection Stone, why weren't Tonks and Fred present, since Lupin was (answer: they weren't germain to telling the tale.)The only problem I have with the series is that the first book needs to have a stronger binding. Each time a new book came out, I went back and re-read all the books. So I've read Sorcerer's Stone over 10 times now, and the binding has split. The other books are still intact. I tend to treat my books very gently, so it isn't a matter of abuse, it's a matter of overuse. But they are very enjoyable.
