I first read this a while back, in the collection of the same title, and I've now come across it again, and read it again, so thought I'd make a note of it. My reaction, I think, is nearly the same. The novella is a fragmentary one, interspersing the life of the narrator's daughter with the efforts of the narrator, and her colleagues, to understand an alien language. That language, particularly the written aspect, results from a perspective that sees things simultaneously, rather than with cause and effect. Studying it changes how Louise sees the world, and impacts on the relationship with her daughter, whose life she is able to encompass through this different experience of time. (I'm trying not to spoil things, for those who haven't read it or seen the film.) 

When I first read this story, I was rather more interested in the daughter than the language, and I think I am primarily still more interested in her. I have a little extra patience for the linguistics this time around, but although I find them curious, I have little emotional attachment to them. The sense of wonder is a little vague. The sense of appreciation, however, is not - this is an extremely well-constructed piece of fiction, thoughtful and original and interesting.
