Maybe if this is the first ever anime you are seeing than it could be considered "interesting" or "good"?

But it is OBJECTIVELY bad written and portrayed. It is watched only because of the main secrets which are being kept as such, but in a terrible way, and make no sense actually.

The episodes could actually be at least half the lenght, because they are filled with lenghty, useless and stupid dialogues that could be skipped.

Some important secrets are revealed in the most non-logical way, just like if the writer couldn't be able to find the better way.

You are not able to emotionally be attached to the characters, being many so stupid or worse, thus when something happens to them you couldn't care less.

Some scenes are portrayed like if they should be important while they aren't.

And so on.

Just don't lose your time like me and don't watch it, you don't really need to.
