Harry Potter and the Half Blood Prince is a fantastically well done and richly satisfying movie. Here,we see the darkest and most mature Harry Potter movie of the 1st 6 by far. The charm and innocence of Sorcerer's Stone that so defined Sorcerer's Stone is completely gone now. Harry is growing up and preparing himself to take on his greatest challenges yet. As those who have read the book know,Harry Potter and the Half Blood Prince really has 2 important storylines to it. On one hand,Half Blood Prince is a backstory story where we learn more about Voldemort's past. At the same time,Half Blood Prince is also a setup story as the events that occur in Half Blood Prince in real time are setting up the events of Deathly Hallows. The film does a brilliant job of bringing those things to life. I was especially happy with the depiction of the day Dumbledore first met the young Tom riddle. That was a scene the filmmakers nailed. I was also very pleased with the way the circumstances of the Half Blood Prince's book were handled,both in terms of that 1st Potions lessons and in the scene where Harry is forced to get rid of it.Then the acting was superb. Daniel,Rupert,Emma,and Alan have mastered their characters by this movie. And Michael Gambon gives his best performance as Dumbledore in this movie,particularly in the many scenes in which he and Harry are alone together, Finally,I was immensely satisfied with the climax. Apart from the presentation of the events themselves,the emotional aspects of the climax hit the heart for me. Even after many viewings,I get teary eyed when Dumbledore dies and when the students are all raising their wands in tribute to him. This is a very poignant time for Hogwarts. In this movie,Dumbledore is preparing Harry for what lies ahead as events culminate in the climax that sets up the major war in Deathly Hallows. My only criticisms are that they should have included the memory where that witch shows Voldemort the Cup and Locket so they,as Horcruxes that become important in Deathly Hallows, would be properly introduced in this movie. That memory should have been in the movie instead of the Ron-Lavender and Dean-Ginny stuff,which should have been cut from the movie (and the book) because it added NOTHING to the plot. A few cases mild language,but nothing to worry about. While Harry Potter and the Half Blood Prince is a GREAT movie,it is for high schoolers and older only. This movie includes a scene of chaos as a bridge collapses,drinking scenes,including 1 in which Hagrid and Slughorn get pretty drunk,,a girl touching a cursed necklace,scenes of the burrow burning,a boy being poisoned,Hagrid's hut burning,and an EXTREMELY sad and emotional death. This movie is for high schoolers and older only. Harry Potter and the Half Blood Prince is a deeply rewarding movie that MUST get 5 stars.
