Aww... You could have done such a better ending...
I'm sorry to say that I am a little disappointed... You left a lot of the story unexplained. Some things like who the giants were, why the world got how it was.. and so on.
All-in-all, I thought your series was great, the animation was awesome, some of the best I've seen, and I really enjoyed your storyline. However, the ending was a little lacking, seemed like it was just thrown together and animated quickly just to finish. I'm sorry if you don't like my review, but you could have done a lot better, and I think we both know that.
