Wow! Amazed by this blu-ray collection! I really am:) First of all let me say I didn't use to be a Harry Potter fan until I have started to watch these wonderful fantasy-adventure movies. Then slowly my interest started to grow and it reached its peak, meaning the point I am now. I've collected the first four movies in DVD special edition until this box was bought...Purely incidental it was. Harry Potter is made for Blu-ray and I have to recognize that with new technological experience these movies are more and more growing in my soul. Harry Potter and the Half Blooded Prince seems to be the best and probably what's to come is the ,,epic" we were expecting for so long. Nevertheless all these movies are each a treasure even for us grown ups. The price I paid for this box was a truly bargain. If you don't own Harry Potter on Blu ray, buy it now! No Regrets, 100% guarantee! The special features are present on every disc as one should expect in a huge amount amount of extra minutes, most of them in HD, only partially in normal definition.
