I binge watched season 1 a few months ago on Netflix. It was Japanese with subtitles, which works for me because I can't stand the fucking American voice overs when it comes to anime. I haven't traditionally been a huge anime buff, but I give the highly acclaimed ones a shot, typically. I thought that it was extremely innovative, and for something animated, it did a very good job portraying the horrors of war and annihilation. Writing, dialogue, backstory, animation, all top notch, and almost as suspenseful as the final episodes of Breaking Bad, touche, zipperheads.
