yazza-j it may help to know that as the heroine learned the language of the aliens, she gained the power to see the future.

Okay, the alien language she learns is not constrained by time. Therefore, when she learns the language, she consequently is able to exist in all plains of time. Which is how she is able to to see her meeting with the Chinese general and is able to learn from him how she managed to convince him to stop the attack in the past. Using this information, she is able to give him that information in the past. It was imperative for her to learn this language because the aliens needed mankind to work together as a single unit because 2000 years in the future, the aliens will require us to save them from some unknown threat. Using this language, she is able to learn that she is destined to have a child with Hawkeye who will eventually die and Hawkeye will leave her. Knowing this, she commits to the relationship anyway. Overall, it's pretty retarded but people seem to love it. So what do I know? Hope this helped.

Vingo, your comment made me laugh. Hawkeye!

Most of the confusion stems from the fact that the initial montage where they show Hannah and Louise is not a flashback. I believe this one thing confused most of us viewers. All of those scenes with the narrative are scenes from a future that is yet to happen. Once that is understood, the rest of the movie is reasonably straight-forward.

This is the deepest/most profoundly symbolic movie I have ever seen. I would suggest watching it again/again. Everything in this story/cinematography is extremely purposeful. I could deconstruct it for you, but it wouldn't be as meaningful/fun :)
