Yep, this anime was good. But there were some problems.
1st Animation. The animation was ok. But in some places, the Animation was really so poor. I think the creators should improve the animation a little bit.
2nd the character reaction. The character reaction was pretty good, But in some places, the reaction was making no sense. For example, when the human bodies falling from the sky the character didn't give a sh!te. They were just taking a family picture.
Ok now let's talk about the things that I like about the anime.
1st soundtracks. The soundtracks were really so good. The soundtracks gave me the same feeling of silent voice soundtracks.
2nd the story. The story was incredibly good. In the story, you know that everyone could die. But when someone dies you don't want to believe it.
Overall the anime was pretty enjoyable. And who knows that That kind of deadliest disaster will never happen.....
