Review Detail of Rak in I'm reborn as Harry Potter

the author has come up with many great stories but there is are major flaws in this book. The grammer is horrible, things which could be fixed with simple grammerly or chatgpt. The gender of things keeps changing. then comes the MC, he is taught again and again he is acting stupid and that it costs him his dears and gets torturred for it. He even died cuz of his own stupidity which he agrees he was stupid for in hindsight, twice!! and the what does he do ? does he change finally ? no he keeps acting stupid while saying what he did before was indeed stupid. ROB told him that people in this AU are smarter, then he keeps on saying people are stupid while he himself keeps on getting caught. im ranting because i wanted to like this story so much cuz of the good things it had. but i had enough once he didnt kill snape who caught him to give to voldemort at chapter 31. btw he mostly is surviving by luck till now.
