I have to recommend this drama - it's intriguing, beautifully shot, and located in a beautiful landscape with its own character and force. the music is beautiful too. Acting outstanding and great characters for all the supporting cast - none are simply there to perform a function and then evaporate - each is a defined person, which is lovely. All the cast, really, were stars - "supporting actor"? ... who - no, they were all substantial roles and some of them, heartbreaking.
The landscape itself has a crucial role, and cannot have been easy to put onto film - kudos to all involved in capturing a sense of this mountain - though I suspect it is a pale shadow of the real thing.
Well produced, obviously, and well written, though the plotting depends a little too much on concealing information for a later reveal and on time-slips, which could also be confusing.
