>>56396577People should be happy if they had a good childhood and feeling nostalgic is valid. But if they're complaining about how much better it used to be, then imagine how sad and pathetic their present lives must be, especially if they can't move on from a kid's franchise like Pokemon that isn't bringing them the same joy as an adult.
If you're an adult and still enjoy Pokemon, more power to you. It's the whiners about how bad modern Pokemon is that are the biggest losers in the fanbase.
