Not just YA fiction, but bad YA fiction of the breed we've seen since garbage like Hunger Games started masquerading as entertainment for adults. The purile, self-centered characters are so intolerable that I'm starting to think the writers hated them as much as I did. When the eldest character in the merry band dies in a poorly choreographed chase scene 3/4th the way into the first episode, nobody even seems to have realized he died. Probably the right move; being essentially written out is preferable to having these lamentable actors try to play at actual human emotions.
