So it's not popular to some. But I like it, it deals with slice of life with kids who are considered outcasts and the odd ones in their school (coincidently, it has a familiar name to one figure and it has it's rules)
If anyone paid close attention, there's more to this series than meets the eye. There are some cases, that some of them do make mistakes while some adults can go overtop and don't get the kids.
It's a matter of understanding one another, it has some quirky moments and bits of coming of age.
I agree this is underated, perhaps if it got revamped or a reboot, it could be bigger and better. Just give it a chance.
