Twilight is such a good example. First, when something is that popular, it’s automatically a bit sticky not only because of its ubiquity, but also because there is the question of why it’s so popular, especially if it’s not that good. Like what is this saying about the culture at that moment.
Furthermore, there are the layers of subtext, which I think are especially sticky when you cannot tell how much of it the author intended. In Twilight there is the surface-level weirdness e.g. about Edward comparing the sin of premarital sex to the sin of murder, and then you learn Stephanie Meyer is Mormon and you see that ideology, and then you get into the really weird stuff where you’re like, Stephanie I can’t tell if you thought this through girl and my goodness I hope you didn’t.
