The way i can describe this movie is...2001 meets Apocalypse now. It has some pretty interesting ideas at its core, the challenge of being better than the one who raised you, and how you can surpass them. But ultimately this movie is too strange to put into words.
Maybe you'll have a much more clear picture when you see it, i can recommend it for its scenery and its good master of noiseless space scenes, the story is gonna be up to you to decide.
