This is probably my favourite book in the series. I read the books late and after I had watched the films (I recommend reading them first). One of the reasons that it is my favourite book is because this is one of the most least explained films. Why the hell would they not explain why Sirius and Peter are able to be an Animagus???And also in NONE of the films do they ever explain that James Potter is also an animagus and transforms into a stag, hence the reason Harry's patronus is a stag. They also haven't shown they form of Harry's patronus at all in this film. There are loads of other reasons why I have this film a 6/10. It's not awful, like I said I really enjoy watching all the films, but this particular one really gets on my nerves in terms of content from the books.
