I don't consider the Harry Potter Wiki as reliable. Because according to its canon policy: if Rowling hasn't specifically denied something about a film in the Книги или in other words, whatever the films say is to be first and foremost promoted in the Статьи as a canon fact instead of the books' facts.
In my logic it should be the other way around. That the books' canon should be promoted first and foremost - exactly becasuse the Книги are the tier 1 canon and the Фильмы only the tier 2 или 3 even - and because we can not be sure what about the films are from Rowling's hints and what are just the film makers' interpretations. By all chances it may be promoting as canon something that is totally fanon.
Apparently the Wiki's policy is that silence is a sign of agreement. I would rather trust words, because silence can have so many other reasons too. And how likely is it that Rowling would bother to point out everything that the film makers made different than her intent is? Not likely, because during the productions she already gave them everything she felt necessary and whatever they made with it, they had the right to with the creative lisence. It seems to me Rowling has publicly прокомментировал(-а) only on mistakes that hold some special amusement или other feeling to her personally: such as the movie Dumbledore talking about a girl though in her intent Dumbledore was gay.
The Harry Potter Wiki says that Barty Crouch Jr. took part in the torture of the Longbottoms even though according to the book, he may have not and Rowling even put weight on it and never confirmed the truth. Did Rowling tell the film makers her intent and did they use it? We don't know, yet that Wiki chooses to promote the movie's decision as canon. Even though the film makers evidently turned Junior's character and the entire trial scene upside down anyway. What in the world makes them believe that it cared about the canon Junior in anything else either?
The way the Harry Potter Wiki is now, it makes the Фильмы the main event and the tier 1 canon, even though that naturally should be the books.
Rowling and her intent is the true canon and thus the Книги she wrote and whatever she does say publicly should be the main Источник of canon facts, and not some Болталка films we don't even know how much she was involved with.
A Wiki which policy trustes and first and foremost promotes a horribly unreliable, barely semi-official information instead of the tier 1 canon, is not something I would trust for canon matters.
