I don't know if I'm the only one who has noticed this, but I have always been bothered by the majority of webtoon commenters. Most of them seem to lack absolute media literacy and don't know how to reflect/critically think on what they consume.
I think this is such a prevalent behaviour, for webtoon commenters to consume and not think or reflect on it at all, because webtoons are generally easy to digest/understand. Unlike other types of media that REQUIRE critical thinking from the reader, most webtoons are easy to read, understand and, frankly, don't require critical thinking at all. However, in my opinion, this becomes an issue when webtoons that seek to present a deeper narrative, emotive, conflictive and not purely morally right, webtoon readers just can't digest that at all.
For some reason they will read it anyways, will not think critically about anything presented to them and proceed to hate/love characters as soon as they are shown on their screen, putting no effort to understand them, and get bored when the plot gets thick and comment "I just want to see [ex: main couple]". I'm currently re-reading The Fox Club, and it's so frustrating to see that the readers are not even trying to understand the story, which is deeper than most webtoons. My favorite, Pink Through The Night, also suffers from this, especially when it came to Oscar AND Luciana. It has happened since I can remember, that someone comment how they hate a character that was just presented and gets a bunch of likes.
