There are very few movies that I consider being perfect. Where plot, story, music, cinematography, dialogue, and actor characterizations, create a completely immersive experience. Watching this movie sucks you in, you feel like you are reading from someone's diary. Stunning scenic vistas.
Well worth a rewatch.

I wrote a paper on this for film school, I'll see if I can dig it up if anyone is interested.
