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?
Also it’s not that it makes you a pre-cog, it’s more that it makes you unstuck in time, Billy Pilgrim style. She was perceiving her life nonlinearly.
