One interesting thing about the movie Arrival is that they actually completely flipped the message of the story in their adaptation!

An explanation of the differences is ROT13 encoded below to avoid spoilers:

Very interesting. I loved both but for some reason I did enjoy the short story better (I'm definitely not always a "The book was better"-type person either), and I think this explains why. I'll have to go and check them both out again and keep this in mind.
