As far as the production, it was a typically good Potter movie. However, the story seemed a bit thin. The main story of the show seemed to be Harry and hermione trying to gain the affection of Ron and Jenny. Seemed more like filler material to me. Rowling et. al. trying to tie the story together. I think you could have put alot of the pieces into other stories and skipped the 2.5 hour 1/2 Blood Prince.
