Movies from books will never be equal. Movies will always be the lesser one because it couldn't do nor even attempt to show what you can imagine while reading the book. I felt that the movie didn't satisfy me, because the first movie set the bar really high and as the next franchise goes on, it could not reach what it had reached before- it felt like the quality degraded rather than to raise it, but nonetheless it was something worth watching. I did not feel it was a good ending for Harry Potter, but a good connection from where it started.
As a fan, I wish they made something even better than this, If I was the QC of this project I would have rejected it. There's so much potential that the story could present, yet the movie shown only partial of it. There's so much emotion that could be expressed, yet none was presented in the movie.
