I have read all the books and seen all the movies so far. I think this book had the potential to be the best movie, since it has this huge dramatic suspense built up of who is the half-blood prince and who is Draco assigned to do away with, not to mention the love interests. However, it fell flat; maybe because there were just too many sub-plots going to make an effective film. One thing I enjoyed immensely, though, was seeing all the places we are going to be able to go when Universal Studios finally opens their Harry Potter world theme park -- I can barely wait!!!
