I know a movie shouldn't have to explain every detail about it's aliens or whatever, but I found the aliens a bit inconsequential in the end. They show up, teach Louise the language / non-linear time thing and then leave. There is ultimately nothing about why the 'gift' is spilt into 12 besides a vague suggestion humanity needs to work together, or how it's going to be useful in 3000 years. I also didn't quite get how the aliens knew the Chinese changed their minds and started sharing.
"I wasn't going to change my mind until you said the last words of my dying wife" is soooo corny and played out in a time travel story, especially when we (or the typically audience at least) don't know what the words are. The idea she might not have been died yet is interesting but seems like a reach as there's nothing to suggest that and, again, we don't know what his super persuasive phrase is.
In the end the film does hang it's hat on the view of time which I did think was well done, even if the twist was hammered in for 5 minutes more than it needed to be. I liked it a lot but could have done with the main plot being tied into the twist a bit more.
