I'm glad I found this unexpected gem. The texture and feel of the film is consistent and perfect. The acting is very good, with minimal dialogue. The fear is there and the scares are there, made all the more real by the gentleness and emotional weight. Especially startling is how the composition of filming, lighting and sound made the girl blend perfectly with the water she inhabited. There are some very chilling scenes, and this is a movie that will stay with me in a good way for a long time.
The music is beautiful, too.
