The Guardian (UK) newspaper is featuring a great series on their website, “Best picture Oscar hustings” in which each feature describes the reason why that specific nominee deserves the golden statue.

I like this feature because it kind of proves what many, including myself, have said for a long time – so many pictures are worthy to be considered “best pictures” for a variety of reasons. In the end this is purely a subjective judgement which is nothing else, initiates a great debate and discussion but in no way should be seen as an absolute or authoritative declaration.
