Is it fair to criticise a game for being too hard/easy?

I've always thought that almost any game should have a difficulty setting from the beginning, to adjust to anyone. I mean, if people want a more relaxed experience, go for easy. If they want a challenge, go for hard. That could pretty much work for almost any game.

How would you accomplish this in a platformer? Not Cuphead mind you - like a .... Mario 64?

Fair enough. In some games isn't possible to have that option. Platformers like Mario 64, for example. In Cuphead would be as easy as having an option to lower the bosses HP. I know that this doesn't work for any game available, but it'd work for many of them, the vast majority I'd say.
