As a big fan of the Harry Potter books, I must admit I had pretty low expectations for the sixth movie, "Harry Potter and the Half-Blood Prince." Especially after being disappointed by the fifth movie's inability to resemble the book or smoothly further the plot, I had little hope that this more significant and lengthy part of the story would be any better.
But I am happy to say that this movie completely took me by surprise and was extremely enjoyable.
This book is where the story of Potter and his Hogwarts' friends really picks up. All the previous books and movies have their own plots and their own endings even though they are all connected as Harry's story. However, I have always thought of the sixth book as simply an introduction to the seventh. Voldemort isn't even in the sixth book and there is no real resolution. I think J.K. Rowling, as well as the producers of the movie, deserve praise for making this interlude so exciting nonetheless.
