Denis Villeneuve's Arrival
So I just finished watching arrival for the first time and can you guys help me in understanding it.
The purpose of the heptapods was to gift their language to Dr. Banks that would allow humans to help them in future. Also Dr banks gains the power of visions through which she can foresee the future (her relationship with Ian and how they'll give birth to a daughter and she'll die). Now for Banks time is non linear and whatever happens in future and she envisions it will affect the present (as we saw in the general shang scene).
But the first scene of the movie is about Banks daughter's death, about which she gets to know after her birth but we as the audience see it in the opening scene of the movie
