We meet Harry trying to meet a girl but cannot because Professor Dumbledore suddenly appears and teleports them to see a former teacher of Hogwarts, Horace Slughorn, saying that it is critical that Slughorn should return to Hogwarts.
Later, after exiting Fred’s and George’s shop, our trio see and follow Malfoy to Borgin and Burkes wherein they observe Malfoy meeting Fenrir Greyback which leads Harry to suspect that Malfoy has joined the Death Eaters, though Ron and Hermione are doubtful.
At Hogwarts, Professor Slughorn returns to teach Potions, allowing Professor Snape to take over Defense Against the Dark Arts; Harry and Ron are now able to enter Slughorn’s class. Harry obtains an annotated copy of the potions textbook which was previously owned by the “Half-Blood Prince”, allowing Harry to shoot to the head of the class and win a small vial of felix felicis (liquid luck).
Ron also joins the Quidditch team and, with Harry’s help, becomes a Gryffindor hero.
Dumbledore tells Harry about Horcruxes, and how they safeguard a portion of the creator’s soul, granting the wizard immortality for as long as his Horcrux remains intact, and discloses to Harry the true purpose for Slughorn’s return; he asks Harry to discover what Slughorn really told Tom Riddle about creating Horcruxes when Tom—now known as Voldemort—was at Hogwarts.
Despite putting so much effort into the scenes and backgrounds—by using real books and real stone, for example—the picture is so dark that it makes no real difference whether there were real books or a backdrop with books painted thereon. Despite that, this is a good movie; nonetheless, I still believe the Harry Potter books to be superior to the films, and this one is no exception.
