What an ending... (spoiler)
Religious themes and practically all subject matter aside, the final few moments of the film are among the most emotionally exquisite I've seen.
The way no words were spoken and he helped her die, whilst looking at the elliptical shape above her... incredible bit of visual storytelling there. I can't really put into words how beautifully that was put forth.
The movie had its flaws, as all films do, but honestly that ending evoked a visceral reaction in me that was almost entirely beside the narrative of the film. So deeply, deeply moving and heartbreaking. Incredible.
