Halfway through (even though I saw the movie twice), I felt as if this book's not even close to half the quality of Prisoner of Azkaban, but as I reached the ending, it was a mix of pure bliss and melancholia. The foreshadowing and the setup! JKR did an amazing job at it.

Also, someone bewitched me with an imperius curse. I cannot, most absurd, stop myself from reading the series. Thirteen days in and done with four books! Mind you, I am quite a slow reader.
