Just writing because loads of people did a bad review.
This anime is not a masterpiece or something that will mark or change your view of the world. However, it is still enjoyable. I'm guessing the people who reviewed it badly had high expectations of this anime.
The whole setting its normal. Not a flawless universe, not characters doing the most intelligent action, it actually shows how real people would react because they don't have the capacity to be wise.
So, to who I don't think they will like it:
Anyone who wants stimulation.
Please who like skipping to the important parts instead of watching everything.
People who everyone needs to act or do or whatever like this or that because that's what they support to do mindset aka overanalyzing
People who want a perfect anime
People who want to escape in fantasy
People who will enjoy it:
Anyone who just want to see a fantasy anime without expectations.
