As seen in the wildly mixed reactions to the film Watchmen earlier this year, adapting a beloved work for the screen is a tricky endeavor indeed. The Harry Potter films have had an increasingly challenging task to fill; the books become longer and more complex, demanding that the filmmakers find creative ways to decide what material is expendable, what is not, and above all, how to present the stories in unique and enjoyable films.

The sixth installment of the series is a success on almost every account. Many plot points and minor instances are lost to contain the film to its 2 1/2 hour running time. It is for the most part easy to follow and understand for those even slightly familiar with the story, but it will almost certainly leave those unacquainted with the series bewildered and confused.

This is by no means a fault. On the contrary, the filmmakers know their audience is all but guaranteed to be familiar with Potter’s magical world and never pander to viewers by pausing to explain things.

Harry Potter (Daniel Radcliffe) returns to Hogwarts School of Witchcraft and Wizardry for his sixth year amidst increasing danger from the dark lord Voldemort. Happening upon the book of someone called the Half-Blood Prince, he is thrust back into the slew of mysteries that haunts the halls of Hogwarts. All the while, his nemesis Draco Malfoy (Tom Felton) appears to be in league with Voldemort. In addition, Harry and his friends, Hermione (Emma Watson) and Ron (Rupert Grint), must also deal with raging hormones and budding relationships.

As the year progresses, and the stakes are raised, it becomes clear that someone very dear to Harry — or possibly Harry himself — will have to make an unthinkable sacrifice.

The film is a technically stunning, directorially superb adaptation that will no doubt delight fans, both hardcore and casual. Director David Yates is a masterful stylist, seamlessly combining impressive visual effects with grim, elegant footage.

The movie creates a mood that alternates between the whimsical and the intense. Maintaining this balance throughout its run time, it manages to build a look and feel that surpasses most of the mature films that strive to create a similar atmosphere.

The cast, as a whole, comes together better than it has in previous installments, but it is Radcliffe who bears the brunt of the film. Luckily, he’s matured into a strong, young actor well deserving of the title role.

On the whole, this sixth film is an excellent and bold new chapter in an already well-received series. It is the last complete Harry Potter film before the two-part conclusion is due out over the next two years. With Yates on board for the final installments, and the bar set higher than it’s ever been, Half-Blood Prince makes the upcoming Harry Potter and the Deathly Hallows the most anticipated diptych since the two Matrix sequels.
