This in my opinion was one of the best books in the series, this book really ties the whole series together, bringing to light Voldemort's back story and including the best action scenes of the series. Imagine my diappointment when watching this in the cinema a full 2 years after the last film and they had neglected to put at least half of the book in. Where were the memories of Riddle's childhood and progression into becoming a dark wizard? Where was the speculation over the Half Blood Prince's identity? Where was the huge battle scene? And why did they seemingly sacrifice it for a scuffle at the Weasleys? All questions I'm sure Harry Potter fans have asked.
The acting of the younger members of the cast is, as ever, terrible. While Rupert and Emma do seem to be getting better Daniel seems to be regressing, I saw him on stage 2 years ago and his performace there was much much better than this. The older cast members, particularly Snape remain spot on, with Jim Broadbent doing an amicable job as Horace Slughorn.
The parts of the film that they did get right were brilliant, particularly the cave scene, it's just unfortunate that the rest of the film was not of the same standard.
A disappointing film, hopefully the next two will be much better, roll on November!
