Harry Potter and the Half Blood Prince is probably the most intense and sad parts of all the other Harry Potter movies. It shows us that Draco Malfoy, whom claims that he doesn't have a choice in killing Albus Dumbledore, and that if you really want to know why he didn't have this choice, then you should go and read the book. And one of my most favorite parts, we're where all the Hogwarts students gathered around Dumbledore's bodies, and lifted there wands in the air.
