The Pokemon games have had good, great, and bad iterations just like any other franchise that has the kind of staying power that it has had. Whether people personally enjoy them, or value the small but cumulative changes that have been made to the type of story and games that they are, is a completely different story. To me, HeartGold and SoulSilver are great games, as are Emerald, Platinum, and X/Y. I wasn't a big fan of Sun and Moon or Black and White, but they still are widely regarded as at least good games. People are allowed to have high expectations and be disappointed that they aren't met. That doesn't make them "screaming man babies".
