Harry Potter and the Half-blood Prince

I still haven't watch this movie that I've waited years ( I think so). Most of my friends that have watched this movie said that this is a boring one! I don't know because my sister said so too when I wanted to watch Harry Potter and the Order of Phoenix some years back. The thing was, I enjoyed myself very much seeing that movie! How can she said that the movie was boring?!!! Therefore, the same thing goes for this new movie of Harry Potter and I made a conclusion. I think that maybe those who said that this movie is boring might be the ones who didn't read the book at all! well, for those who doesn't have a clue on what's this movie/book is about, let me give some review:"The deeds of Voldemort's Death Eaters are spreading even to the Muggle world, which is enshrouded in a mist caused by Dementors draining hope and happiness. Harry, turning 16, leaves for Hogwarts with the promise of private lessons ... More with Dumbledore. No longer a fearful boy living under the stairs, he is clearly a leader and increasingly isolated as rumors spread that he is the "Chosen One," the only individual capable of defeating Voldemort. Two attempts on students' lives, Harry's conviction that Draco Malfoy has become a Death Eater, and Snape's usual slimy behavior add to the increasing tension. Yet through it all, Harry and his friends are typical teens, sharing homework and messy rooms, rushing to classes and sports practices, and flirting. Ron and Hermione realize their attraction, as do Harry and Ginny. Dozens of plot strands are pulled together as the author positions Harry for the final book. Much information is cleverly conveyed through Dumbledore's use of a Pensieve, a device that allows bottled memories to be shared by Harry and his beloved professor as they apparate to various locations that help explain Voldemort's past". Got it??When they don't understand the plot and what was this story is about, they'll say it's boring and it is unacceptable for me! Seriously... I'm not that avid fan of Harry Potter (am I not?) but then again, I love to read the books and watch all the movies over and over and over again XD.. Am I really not an avid fan??Hmm.... let me think.....
