From the very first shot of the movie I was captivated, the story is so deeply personal and psychological, it uses space as just the means of which to tell a story with such a powerful message. It's different from any other space movie I've ever seen.
Oh, and don't even get me on the cinematography, it was some of the best I've ever seen. (Update, just checked who did it, makes sense. Frick you Hoytema, you gorgeous son of a gun)
