This is a lovely film
I saw it in the Cinema when it came out and re-watch every now and then when I'm in the mood. It's not just the cleverness, or perhaps conceit(?), of the language as a tool it's also about her courage. To do what she did at the site but also, more so, to have and love a daughter knowing the outcome.
And it's beautifully shot and the music is just right and Amy Adams is perfect in the role and everyone else is good too - and I guess the director got it right (though I'm not too sure about some of his other films).
