This show says a lot. And I totally understand that a lot of people won't like it. That's totally fine! But... all of the negative reviews really seem to miss the point. Give the show a chance. If you really don't like the first episode, stop watching it!
Not everyone will like it, but that does not mean it's awful. The premise is incredibly unique, as is the art style, and the way the episodes are made in general. The format changes a lot, which I personally find super interesting. More than that, I love that it shows people reacting to the end of the world so differently than most media. There is still order. People aren't just fighting one another, there traveling and doing things they only dreamed of. The world is ending, but this is not a dystopia.
