This is interesting because it did annoy me a lot in the films, particularly after PoA. I have problems with the fact that Hermione seems to be the 'perfect female' in the movies when her character is practically dripping in flaws and unsavory (for want of a better word) character traits. I rather prefer the book!Hermione who was more rounded and balanced.

Another thing I hated was that Kloves spent too much time shipping Harry/Hermione, so much so that when the time comes to ship Ron/Hermione to keep with canon it seems forced and rushed.
