You're making the assumption that everyone who states something is overrated is making that comment because a game didn't resonate. There's plenty of games that I love that I think are overrated, because it can also be used to describe something you believe gets too much praisd.
For example, Super Metroid was the first search action game I ever played. I own the soundtrack on vinyl and I still remember the feeling when I figured out wall jumping. One of my favorite games ever. It's also regularly described as either the best game ever or the best Metroidvania ever, and I think that goes too far. The default button mapping is cumbersome, aiming is clunky, and 90s pixel art (while impressive) is not the peak visual achievement of gaming. I think Hollow Knight, the first Ori, Dread, and SteamWorld Dig 2 surpass Super Metroid in so many significant ways that the praise Super Metroid often gets has veered into overrated territory.
I don't if you'll read all of this, because I believe you insinuated I was braindead and dumb earlier in the thread. But not everyone who describes something as overrated is saying that because they believe everyone who likes a thing has poor tastes.
