Not the best of the series, but not the worst either. The end is extremely good - I've been waiting for that death since I first read Philosopher's Stone, and I always thought it would come at the end of book 6. (It's always nice to feel smugly justified when predictions turn out correct.) But apart from the end and the failed horcrux trip, it's fairly... unmemorable, I suppose. Don't get me wrong, I enjoyed reading it - 3 stars is "liked it" and I did. But those good things I just mentioned took up a very small part of the book, and a lot of the rest was filler. Mostly entertaining filler - although while I liked seeing Ginny get more of a personality, I was only very mildly interested in all the teen angst and romance - but filler all the same. It's no news to anyone that these books got hit badly by a case of page inflation around Goblet of Fire, and though I did like this, I can't help but wonder how much more effective it would be, how much more punch it would have, if the bloat were cut so that Prince had a similar length to Azkaban, which remains the best of the bunch.
