Wow, what a poetic film. It's very much the kind of poesy rife with metaphors, hidden meanings, artistic indulgences and intimacy that you'd normally find in literature. The story would lend itself perfectly to a full analysis, as many different things could be taken out of it depending on context and perception. The ending has a slight "the Studio messed with it" kind of feel, but contrary to custom, it's actually handled well and ends up making sense in the grand scheme of things. The acting is excellent but very subtle, the cinematography is original and well-handled and the pacing is generally excellent.
All in all, literature fans would definitely get a kick out of this, as would anyone looking for one of those rarer intelligently and silently poetic films.
In a sentence:
An excellent and very deep script is supported by great acting and cinematography, resulting in a very smart little movie.
