Two pees in a pod...SPOILERS

At first i was confused about what this movie set out to do, and stil i'm not completely sure.

But one thing i have realized, that after reading this board i've found many others haven't, s that they tried their hardest to make these men as alike as possible. Even at the expense of plot.

At the start of the movie both men are heavily covered, black hats and bear pelt coats, but throughout the movie each forces the other down to the bare necessities. Gideon through force, Carver through endurance.

Both men are shown as evil, and as good. And by the end they see that no matter how much they struggle, and how far they run, they will both just be the same. And the only way they can change is to leave their past behind and head as far away from each other.

As you can tell this isn't the most refined theory, but it cleared my head, when i realized the movie doesn't just jump into extreme symbolism from nowhere. Its everywhere just some more obvious filming techniques taken for more depth.
