I saw “Harry Potter and the Half-Blood Prince” twice: once with my siblings, and once with my friends. I re-read the book a few days before, just to refresh my memory with the story (not that I’m quite unfamiliar with it haha).
There were many liberties taken with the how the movie was made, as with the previous ones. Some things were changed to fit the movie’s flow and make away with heavy explanations, like how it was Luna who discovered Harry on the train instead of Tonks.
There were also the addition of scenes that weren’t in the book, but fit well in the movie by setting a tone that shows how serious The Deathly Hallows will be. Also, there are scenes added that may not be in the The Half-Blood Prince but will be in DH, like the opening scene at Diagon Alley and when Snape was talking to Dumbledore in the tower.
I enjoyed the banter and humor of the movie, but felt that the action was a bit dull, and everything after the scene where Harry got the memory was rather anti-climactic. I suddenly lost all interest in watching it and wanted to have more of the humorous moments. I wanted to see more of Ron (the part where he ate all the chocolates up to the part where he was at the hospital wing is among my favorites), more Quidditch, more of the Weasley’s Wizard Wheezies. But I suppose that can’t be.
The movie wasn’t quite what I expected, and I wasn’t that at all thrilled with the latter part of the movie. Dumbledore’s death was sort of “meh,” and I was far more moved when Slughorn said a few words for Aragog (must be the mountain shot). I did like, however, the part where McGonagall lifted her wand to cast Lumos, then everyone did the same.
On the whole, I did enjoy the movie, despite my nitpicking. I did think that for a moment, I was watching “Lord of the Rings” when they went to get the locket.
