Fans will be sadly disappointed at the numerous inaccuracies, as will future readers, seeking to avoid reading the entire series.

Rating: 6/10 (17 July 2007)

While it doesn't achieve the accuracy that I have come to expect from the first three movies, Harry Potter and the Order of the Phoenix does convey most of the book. Inaccuracies abound, and the movie fails to mention key points in the plot, such as Dumbledore referring to the chamber in which Sirius dies as the "Death Chamber", and Sirius giving Harry the mirror (which may not matter).
All-in-all, I found that, while the movie did succeed in telling most of the story, it fails to cover many aspects, possibly leading people hoping to watch the movies instead of reading the books astray, and leading to future confusion in the plot, as well as disappointing many readers.
