It's not because it's not pretty; the cover is, objectively, very nice looking. Good colors, good font choice.
Perhaps it is because I'm bored of passive covers. Is everybody panicking in the days before the apocalypse? Trying to figure out what to do? Or are we just rolling around passively in a meadow?
Now, I haven't read the book; maybe the scene does involve a couple on a meadow, and I do like how determinedly the girl is looking up from the cover. But for a book that's trying to be original among dystopians, it's been trapped with a very cliched contemporary cover. I don't get dystopian from it at all.
What do you guys think?
