Why do people call Erased overrated already?

*Possible spoilers* The pace was amazing, I saw good development, the soundtrack was just beautiful, the art and animation was gorgeous, the plot was fantastic and touching... I could go on, which says a lot about this anime. I'm guessing it's because they didnt get the Satoru Kayo pairing in the end, which I can see as an issue since I was upset too, but I understood why it had to be that way. I've seen many dozens of quality anime and this one tops them all in all kinds of ways. It just sucks to see people legitely not enjoy this masterpiece, I don't know if they just didn't give it a real chance or are just heartless...
