This anime is an example of awful execution.
The writer seems to have no idea how to put together what they wanted to create.
A lot of the dialogue is extremely awkward and most of the characters are very annoying and/or socially crippled.
It's full of clichés and borrowed elements which are amateurishly stitched together.
It has some good ideas, most of which are very unoriginal, but with the right execution could form a wonderful story.
Shame the execution is so horrible.
The set-ups into various plot points, which are suppose to be meaningful, are so poor that one's enjoyment suffers greatly.
A lot of people brainlessly just watch and go along with what's happening without thinking about it, so the awful storytelling and design won't bother them that much.
Do I regret watching it? Not at all.
Honestly, the anime was kind of interesting to watch, even if I had to spam my friend multiple times about how awful the anime is.
One can learn a lot from this anime. How to not tell a story, for example. And how to not develop characters.
