The Daily Beast has a good article on Inside Llewyn Davis, which I saw on Friday, and why it was generally snubbed by the Motion Picture Academy. An excerpt:
Throughout, you feel the bone-chilling cold of the streets and Davis's loss. This isn't a film about conquering demons or surmounting impossible odds, it is a film about losing and losing more, the chipping away of character and of hope. It is about losing your dreams, not achieving them, life shrinking, hope diminishing, aspiration dissolving.
