Mayoiga isn't bad, is different.

Mayoiga is a "weird" anime, clearly not intended for any public. If you plan to see it, skip this review, I will talk about the entire series and my general point of view after I have seen it. It will have spoilers.

In the first place, the audience it is aimed at is a public with a depressive tendency, this is the clear case of Japan, being one of the countries with the highest suicide rate. This is why some of the people who see it here do not quite understand how it can be so "bad".
No, it's not bad, you just don't know how to understand it.
It is impossible to deny that it has a large number of characters and most do not have any type of development:

The coumple in love end... exactly the same?! What happened to the one with the heels and who remembers her? And with the 3 Yuunas?

Also at some points it stops being interesting and loses all that mystery in the series about what happens or what happened in that town.

basically since it is discovered what the Nanakis are

Despite this, the series' story is perfect dealing with the issues it wants to address. As I mentioned before, it deals with part of the problems that lead to depression. That feeling of wanting to flee and start a life from scratch, stop paying attention to those problems that have plagued you for years and can simply escape from them. It seems like a utopia, but what this series really tries to do is make you see that you have to learn to live with your past and your problems, learn from them and try to prevent them from happening again. At the end of the day, our experiences are part of us and that will always be the case. That is the message of the series.
Clearly this series is not going to be your medicine to deal with depression but it is already more useful than all those anti-depression ads that sometimes all they do is play down the issue or treat it as if it were much worse than in reality is (as in those cases that believe that by having depression you want to commit suicide).

Returning to the topic of the previous spoiler,

The Nanakis are the personification of those traumas that the characters have and the only 2 ways to overcome them are to escape and lose the years of life that managed to create those traumas (as seen with Kami-sama) or by accepting them and living with them knowing that to Although they had made your life impossible, now you are different and you can face them (the case of those who left on the bus). Even so, there is also that 3rd option within the series, which is to continue ignoring them until you disappear (transferred to reality as suicide) or decide to do the 2nd option.

In short, the series is not primarily about its history, but about its teaching. That is why I think it is different, not a bad series without coherence (that I do not take away part of the reason) It has a much greater message for those who are able to see it before having read this review because how you are really going to understand them is when you you realize, not when they explain it to you.
