Harry Potter 6 is disappointing!

I wasn't much of an avid Harry Potter reader until I saw Movie 4 of the series. Knowing that the movie had missed a lot of fine details I took upon myself the endeavor of covering the backlog and engrossed myself into frantic reading of the books. Book 5 many said was disappointing but I really didn't dislike it much, thou I was irked by the sudden transformation in Harry, who keeps on yelling at his friends and teachers [J K R plugging in the CAPS letters every now and then - leaving the reader very frustrated]. Book 6 disappoints me no end. Never have I read a book or seen a movie in which the main character has so little to do.

There is nothing special Harry does in the book - he is twice humbled by Malfoy who till now was nothing more than a rogue in the school, all of Harry's brilliance in potion making is due to Snape's book, proving Snape's genius in the subject at Harry's age. Neither does Harry stand out as a role model. He has this constant habit of disobeying instructions and carrying on in his own manner. Neither does he take efforts to practice occlumancy nor does he perfects the non-verbal charms. Both these skills taught to him by Snape would have been useful to him in his skirmish with Snape in the climax where Snape effortlessly dodges each and every curse and hex Harry throws at him. The book in which Ron, Ginny, Hermione and other members of DA fight the death eaters, Ginny and Ron win the Quidditch house cup for Griffindor, Dumbledore gets rid of one of the Horcruxes, Malfoy plays his role in the Death eaters entry into Hogwards eventually leading to the death of dumbledore - Harry is nothing but a spectator.

It is not clear in the book if he has learned the Unforgiveable curses, he is still not good at apparating [he can fly though], Occlumency -no, non-verbal charms - no. Now eventually if Rowling expects her chosen one to finish off the dark lord, I guess she has left a lot for Harry to do in the Last book.
