I thought the movie was rubbish! the worst movie in the series so far. i loved the 6th book, its my favourite in the series. the movie left out a lot of key moments and summerised a lot of the plot.
Alot of the book was centered on dumbledores lessons and in the movie you didnt even know harry had private lessons with him, only that he went to the office twice to see memories. dumbledore didnt tell him the significants of the lessons and with the information could defear You-Know-Who.
Another aspect of this book was the whole mystery of who the half blood prince was and you hardly saw that and how much the writing in the potions book helped harry in class and how he thought it was his parents book etc.
I also thought the graphics were crap. it was rly dark throughout the film and it lacked the quality that attracted me to the other movies.
The acting was also crap!! snape was supposed to be rly sharp and pissed when harry used his spell on malfoy and later on him. dumbledore was supposed to be all nice and sweet hearted and have all his theories about voldemort but they acted like he had no idea about the horcrux. Harry was supposed to be crying his ass off about dumbledores death and all heart sick with ginny which he wasnt, he acted retarded as if he had a stick up You-Know-Where. narcissae was supposed to be crying all the time aswel when she went to see snape but was all together emotionally, hermoine cried a lot which she didnt in the book, she was supposed to be pissed at ron and just ignored him. Ron was the only good actor in the film.
The didnt even include moaning myrtle! :(
The fight outside the burrow never happened in the book, they just made it up and they completely excluded the fight in hogwarts! And....
THERE WASNT A QUIDDITCH MATCH!
the movie was an even bigger let down than twilight!!
