When Harry first has the Half Blood Prince's potions book, his signature is in the front of the book. When Ginny takes it from him, she reads his signature from the back.

I now know the feeling op disappointment.
24 July 2009 | by (Netherlands) – See all my reviews

I've been waiting for this movie for a long time since book #6 is my favorite of the series...Never have I been more angry or disappointed after watching a movie. I feel like Kyle (southpark) did after Indiana Jones came out. I feel like the HP series just got raped.

In some miraculous way Yates succeeded in leaving out every single great scene from the book. And the ones he did put in the movie were less than shadows of how they were written. Thinks that wouldn't even take up more time were changed and ruined. I had heard the Gaunts had been taken out of the movies and I wondered how you could ever justify such a change but it was just the tip of iceberg wasn't it? You managed to make every scene lose its power and make a mockery out of the characters and the story and the logic.

Harry Potter movies are supposed to be like riddles, you get subtle hints and in the end everything is supposed to come together but there was nothing like that here, you just threw it all out into the open. I can't even begin to name al the mistakes you made since my mind is trying to suppress the memories but I'll try to write some down all the same.

1: First scene, totally unnecessary, the way it was written in the book could have easily been shortened to the needed length but you made an entirely new, useless scene. Why not just a quick scene at the Dursley house?

2: Getting Slughorn, the entire reason Slughorn came back was left out, they could have added 3 more lines about how everyone could find slughorn when he was on the move but no, who needs a decent motive? If bringing Harry along was enough, then why go to the loo at all?

3: Fixing the room, why not a short shot of the wizards back to back like in the book, would have been nice to see that at least 1 thing of the book came back in the movies and it wouldn't have taken more time.

4: Horace Slughorn is supposed to be smaller than Dumbledore, and have a beard, and he was head of slytherin house, not some teacher. Why change this, didn't save time and now we have him saying that certain students weren't his students...which was ridiculous, one line about head of slytherin house could have fixed this.

5: Why wasn't the Weasley house protected? and why was the house attacked at all? Useless, illogical scene, they could've used that time for more important matters, matters that were actually IN THE BOOK.

6: Ginny's kiss, I will murder you for this one day Yates. That was supposed to be passionate in the heat of the moment, not some slutty move while she was still with Dean. That scene and all the scenes surrounding it were utter crap.

7: no explanation to who Gave Katie the necklace and how Slughorn came by the mead, that was part of the riddle that you were supposed to solve but your lame ass movie didn't have any of that did it?

9: Dumbledore's torture scene, weak weak weak, didn't have a bit of emotion in it, and missed the point entirely of what he was reliving.

10: Dumbledore's death, changed for no reason, doesn't make sense, acted out badly.

11: The worst one...You left out the battle in Hogwarts? Are you insane you little prick. The movie didn't even have an ending. Well I guess since you screwed everything up that lead to that part you might as well go for broke. Seriously, did you even watch the movie?

I see this as one of the worst experiences of my life together with my favorite uncle dying and my first love leaving me. I don't know which of the three is worst.

I want my money back since I paid to see the movie adaptation of the halfblood prince, not some random movie that has characters with the same name.

2/10 for pretty effects, which is all this movie was

I hate you more than Hitler.
