After watching the trailer for Arrival last week, I went and read the source work, Ted Chiang's 'Story of Your Life.' I've been wondering ever if they'll be able to translate such a intimate, quietly tragic story into a feature-length movie as-is. I think, from hints in the trailer, they may have constructed a third act, perhaps one in which the heroine has to make a Terrible Choice -- which would at least be a choice.
I don't know if it's possible to say any of this without spoilers.
sovay, have you read the short story? It strikes me as your sort of thing, given that it's about learning another language and as a result being forced to confront the idea of immutable fate.
