spoilers ahead I felt like the character conflict arcs were contrived and ultimately the idea of learning a language makes you a pre-cog fell flat for me. In science fiction, the big idea goes ‘woo!’ or the characters go ‘woo!’ but in the case of Arrival, nothing really went ‘woo!’
But maybe I’m wrong - what was I missing about Arrival?
Its not. It doesnt try to give a hard science explanation, it gives an explanation of perspective that offers actual insight. Ted Chiang doesn’t write hard science fiction, but it’s very well thought out science fiction, imo.
