I used to be indifferent to the whole Harry Potter concept, but I have to admit the darker the stories become, the more I'm getting involved. This episode is (literally) more than two hours of darkness, both visually and conceptually, to the point of becoming scary at times. The film still suffers from the common problem of all Potter movies: sequences that do not contribute to the story, and can easily be eliminated. Staying away from the books led to a surprise from the tragic ending. Not perfect, but the best Potter movie yet.
