Harry Potter and the Half-Blood Prince

David Yates now really begins to take these stories to a new, potently darker level as "Harry" (Daniel Radcliffe) comes into possession of a book - formerly the property of the eponymous Prince. His skills increase exponentially and he soon begins to question whether he, himself, might be closer to the evil lord "Voldemort" than he had ever thought. The three principals are very much on the same wavelength now; the supporting cast likewise and there is even a little late hormonal activity as the awkwardness of teenage years (remember?) starts to feature too. This film also sees the arrival of Jim Broadbent as "Slughorn" - quite an engagingly enigmatic character and we can easily now sense that the battle lines are starting to be drawn... This is highly entertaining cinema. A big scale production and fine scoring builds on a strong story with characters we now know. A big screen must.
