My first issue with this show is I cannot relate to any of the characters. I'm a 42 year old alpha male. High School's a long time ago and I hated it there. I find none of these characters remotely interesting or relatable until Kento Nanami is introduced.
My second issue with this show is despite all the supernatural powers on display, there's far too much emphasis on just hand to hand combat, punches and kicks being thrown. That's why after nanami was introduced my interest in the show increased because there were characters who had powers that differed from nearly punching and kicking stronger and faster.
This next issue stems from the previous one. The fact that our primary Heroes rely mostly on their fists, palms and kicks to win through the day, despite the fact that the villains have supernatural abilities which seems lopsided. Like I can project poisonous feathers that attack from the sky yet I can't defeat a kid who can only run and punch me in the face?
And there is no world-building to explain any of this. You were given some vague descriptions about how cursed energy works, how there are those who can use it, those who can't and that there are cursed objects with magical powers in them but literally that is it. There is no explanation to any Rhyme or Reason behind any of the random differences in powers, limitations and abilities.
Not to go too much into it, but I also feel this show has bad comedic timing
Like I said in the beginning I like the action sequences, I liked the character design, I like the overall story that the anime is trying to tell. I like everything about this anime except what I critiqued above. It is entertaining to watch. But it didn't secure a place in my heart.
Tl;dr - it's good but the genre has done better
