Harry Potter Half-Blood Prince vs. Movie?

If you have read the book the movie was horrible, if not it was ok. The movies didnt capture what a horocrux was and how it related to the story. It didn't do anything that had to do the half blood prince and how it helped him out. It cut out about the last 3 chapters of the book and instead had daniel radcliff crying. I read on a website that the director didn't want to have to action scene at the end of this movie cuz it would be the same as the 7th movie, which is BS. I also dont like how the dang movies cut out all the characters, like the rest of the weasly family and the other gryfindors. The first two movies were spot on, but after that I have hated the rest
