People would watch this show atleast 5 times and still say it's a really bad show even though they enjoyed it every time they've watched it and still complain about the writing.
The whole point of watching solo leveling is to sit back and relax, this ain't Death note ✌️
Anyway, im not a hater not love this too much(cap) but I don't think the writing is that bad considering other Manwhas that I've read(alot of whole world genre type).
There are only about 14-15 (or more that I've not read yet, or are VERY much overrated that I've not stumbled upon them yet) Manwhas I found to be really good written. And I think it's not because the writing is so peak that people are glazing it, it's just that this has the best artsyle (among some others) and above average presenting and storytelling(as in the pacing and attentiveness, etc).
It's the same thing with the japanese manga/animes. There are ALOT more slops than good written shows, so it contrasts to make the food written ones stand out so much that the good ones keep growing and bad ones keep getting more and more hate.
Just like the economy with the rich and poor lol.
