There is a really good review of this movie by another user (his summary is "imperfect but unforgettable"), so if you can check that out please. If you read it, you will also understand that there is a lot of (background) knowledge/info in this comment. Which begs the question: Do you have to know all of this (like the poem that utilizes the same location?) to fully understand and enjoy this movie? Or is it possible to watch it without prior knowledge?
It's a difficult question to answer. But as it is, I can only answer that this indeed is unforgettable. It's story core is really heavy and while there are some sub-stories interwoven into this, you always have this feeling of uncertainty running through it. Still the characters are not far from blandness and never fully engage you. The story seems confusing (though it is simple enough, it seems to be more complicated), which takes you a bit off it. (or that could be the case, depending on your concentration on it) There is space for improvement on this, though it does not take anything away from the ending ...
