As a movie it's the most well crafted of the series. But as an adaptation of the book, it was by far the worst.

The strongest entry since Azkaban, Half-Blood Prince begins to lay the pieces of the backstory that up to now has largely been hinted at. Memories are a key theme of the film and there is a melancholy feel to the story as characters old and young begin to realise that huge changes are imminent. Amidst all the darker threads however, the film also has a lot of fun portraying teenage angst over relationships and the central trio’s refusal to express their feelings. But it’s Harry’s relationship with Dumbledore that is brought to the fore and after fumbling a little with Sirius, here the filmmakers do a wonderful job of showing the respect and affection the two characters have for each other - it helps to have five films behind this, but Gambon is much warmer and caring towards Harry and there is a much stronger bond shown here that ensures the plot developments hit home when they should. This is also the first film to give Tom Felton something more to do than sneer at Harry and it’s great to see Draco develop into something more interesting than a childish foil to the heroes - his bravado unmasked throughout the film in small vignettes that show his uncertainty and fear. The reveal of the identity of the Half Blood Prince feels like an afterthought in many ways but this sets up the prospect of a great finale.

can’t believe they cut out the most iconic scene: Harry marveling at watching Dumbledore’s cut bod and 8-pack abs swimming through the ocean
