As huge Harry Potter fans, we were so excited to see Half Blood Prince at the midnight opening. It was well worth the wait!! The characters were extremely well developed, and the darker tone of this book was brought to life. At the same time, there was plenty of the series' trademark humor, and the character relationships were a joy to watch.
The only negative is that I felt the Half Blood Prince storyline was given somewhat short shrift. If you hadn't read the books, you might be a little let down and confused at the big reveal.
A very minor detraction overall, though, and definitely understandable given the intricacy of the plot. Two thumbs up!!
