/not reading this work, but I do agree with you, especially for works like ID.
Actually when I meant crappy manga I mainly meant all those degenrate romance manga with good for nothing (literally a good for nothing) main characters with other who was something eventually becomes a degenerate just like the others. Not only that but in most of them they make the world very screwed up with not much adult supervision and protection. I don't get how these manga last several chapters and quite a few volumes while others are cancelled or axed even before it reaches 5 volumes when they were entertaining. Just out of curiosity I read a few of these degenerate manga thinking it might be good because there were alot of chapters. After I started reading them I was thinking "What the hell is this?" "How the hell did this manga last that long?"
