Surprisingly, I actually like this a lot better than Another Earth. I have to say my jaw dropped out of of confusion but after reading the "theories" in IMDB, it can actually make a lot of sense. Definitely looking forward and hoping for a sequel.
Interesting film, quite thoughtful, and strange.
It had the potential to be truly amazing, but didnt quite feel like the writers knew what to do with it, or that it was left deliberately vague for the Donnie Darko effect of the audience writing epic essays about what TRULY happened.
