After I read HAlf Blood Prince the book,HBP movie was not worth?  

It breaks my heart to say this but I absolutely agree. The film did not capture the enchanting elements from the books. For the first time we see the limited acting skills of Bonnie Wright. The scenes between Ginny and Harry were awkward not because they were meant to be, but because there was no chemistry and there was no passion and longing for each other. The only scene that captured that was when Ron and Lavender interrupted Harry consoling Hermione. Because of this, the school scenes felt way too draggy, with little purpose, where as readers of the books were constantly in suspenses as to what will happen between Harry/Ginny, Lavender/Ron/Hermione. Even the scenes with Voldermort felt lacking of sorts, as there is a certain fascination that can't be capture on scene.

I know I sound like I absolutely hated the film, which in a way I did, but I appreciate the effort put into making this film. The detail was amazing, but sometimes, I think that having such detail does not help make good films. My favorite HP film is Prisoner of Azkaban, which many fans hated. The film had a certain artistic value that can't be found in any other Potter film, it brought the audience through an emotional rollercoaster, the pace of the film was non-stop but with ample time for the audience to recover, unlike Globet of Fire.

It is such a relief to have finally found people who also think that the HP movies are not that great! Hi, mrnishalgurung and hi, fallenjinx
I love the Harry Potter books so much and I am terribly disappointed with all the movies. I tried telling some people about this but nobody agrees (to put it lightly) with me. I just think the books were not given justice. There are so many things left unexplained and overlooked that I doubt if people who have not read the books could understand the movies. Well, my husband only watched the movies and he was not very impressed with Harry Potter. I have read somewhere, I am not sure how true, that Steven Spielberg was offered to direct the movies but he wanted Haley Joel Osment to be Harry, so it didn't happen because an all-British cast was a requirement. I wonder how the movies would be like if that pushed through.
I hope someday there would be a re-make. I love HP more than Lord of the Rings, but I think the LOTR movies are much much better.

I was less concerned with the scenes that were left out of the movie and more concerned with the scenes that were ADDED! Specifically the Death Eaters burning up the Burrow. Partly because the Weasleys have suffered enough, they didn't need that too and partly because a big part of the beginning of the seventh book takes place in the Burrow and they ruined the continuity by setting it on fire. Now they'll have to go somewhere else for Bill and Fleur's wedding...and the accompanying insanity.
