Harry, Ron and Hermione are back at the Hogwarts school. Early on, we are introduced to the themes: the half-blood prince has been sent by the "Dark Lord" (Voldemort). This is bad news for Harry. We see Severus Snape make an unbreakable promise to obey the Dark Lord, and to look out for Draco Malfoy, a student at Hogwarts. Later on, the theme begins to focus on Dumbledore helping Harry prepare for his eventual battle with Voldemort. They focus on a question that a young Tom Riddle (who eventually becomes Voldemort) asked Professor Slughorn long ago, and a technique that enables a person to divide up their soul into separate containers, rendering them immortal. Voldemart has learned this technique.
In the meantime, we have some fun with a love potion that's going around the school. It is especially to see its effects on Ron, both as the object of desire and the pursuer.
This was one of the better Potter movies. I enjoyed the plot lines. and the special effects are awesome. I took my nephews, ages 9 to 11, and there wasn't any objectional content.
