While I wasn't a huge fan of what Yates did with the Order of the Phoenix, the Half-Blood Prince was a massive step-up imo, not only was it my favourite of the series, I would actually go as far as to say it was technically the best. Delbonnel's cinematography was outstanding, Hooper's score was subtle, emotional and suited the the film perfectly, the acting (for the most part) was much improved, the balance of the light and dark moments was pretty spot on I thought (I know some argue that the film largely focused on the romance storylines), ultimately it was a well paced, funny and emotionally satisfying adaptation. I realise some people just get pissed off because of the cuts made to the novels, well why not strap the books to the television? I'd rather watch Yates' Potter films than Chris Columbus's childish and uninspired carbon copies of the novels.
