Wow. Everyone misses the point of this film.

Seems like all the reviews are harping on some kind of anti war message (really, how is that a bad thing? I'm still in draftable age. F wars lol). What's really great about this movie is that all this grandiosity with the aliens is just window dressing to the real plot, which becomes the plot twist at the end... and is both challenging and gut wrenching.
We always question ourselves as a species. How many dreams started off on the quest for time travel? To seek answers or to change the past?
Truth is, if you knew what was going to happen, you'd be living a curse. You relive the beautiful moments only to know the inevitable demise of it all.
The aliens in this film aren't doing anything out of the goodness of their hearts, but because of how they perceive time. And because of that, they are slaves to it. They can never enjoy because they need to solve what is to come.
Our freedom is based entirely on our limited understanding of events. Ignorance is the most bliss you'll ever get. If you knew what's going to happen, you can never really enjoy life.
And that's the tragedy of Louise...and what she now endures.
This is what sci fi is all about. Not grandiose messages and whiz bang action, but layering a very human story under the guise of something bigger. It's the only way to be honest with ourselves.
