Arrival is not a Sci-Fi movie
The idea in the movie is that you can manipulate the physics of the universe just by thinking. This is called "magic" not science.
Learning a language can change how you think but it can not change how your brain functions. On top of that, learning a language or making your brain work in a certain way can not give you the "ability to bend time by thought."
This is not Sci-Fi. That's just fantasy. A fantasy tale like Cinderella or Snow White.
Only in hollywood people are ignorant enough to label pure fantasy as Sci-Fi.
And they are asking for an Academy Award for this childish *beep*
