Part of the reason some dislike it is because it's very low-key and simplistic, compared to the massive, dramatic sound of other LP songs. That's also the reason why people dislike Robot Boy, they're just simple pop songs. And there's nothing wrong with that, as both songs are great. Mike's singing in In Between is perfect, because it's serene and dignified, matching the mood of the song.
As for Shadow of the Day, on the other hand...
