I'm a little confused.

So the aliens came and their whole things is that they can see time a non-linear. Awesome! I get that.

So why was it only about Louise and her daughter for the most part?

I thought the danger was 3 thousand years in the future, ok so did the little girl die from that disease? Why didn't the aliens show that to her? Is it limited to how long you're alive, if so do the alien's live for thousands of years?

I was with it up until the ending.

My girl cried and I blew raspberries.
