Still, physicist or not, if you are interested what is time, I couldn't recommend a better writer than Ted Chiang.
The single most crucial part of it was the way her daughter died. In the story, she dies in a (very preventable) climbing accident, to make the point that her mother knew about it and could have just told her not to go (or go a bit later), whereas in the movie she died of cancer, which just completely invalidates the entire point.
It is preventable in the case of not knowing the future (yet it this case we have no idea that it will happen). If we are in the state of knowing the future, it is a part of the reality fabric, it IS, just separated by an interval of time.
It is not that free will does not exist. It is that free will is a perspective (i.e. not something true or false), one mutually exclusive with knowledge of the future. It is like the rotation of an object, which one we can see only one of its facets. In "The story..." Louise learning the different perspective is gradual.
To some extent, it matches some other tropes like Lovecraftian that learning about the Great Old Ones brings insanity. Or maybe it's not that it fries one's mind, but rather - give a perspective incompatible with everyday human thinking.

Strangely enough the Charlie Sheen "The Arrival" is also a really good physics movie. I've yet to see a movie do the SETI/Astronomy/physics stuff better :-).
I love him building a radio telescope control in his attic, using local people's roof satellite dishes as the array !
