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?

Not sure about Mario 64. Tropical Freeze could use more lives and better checkpoints for those wanting it. I know i would want them. Donkey Kong Country returns on 3DS had more lives compared to Wii version. 

Edit: Even Souls games could give more soul drops and less penalty for dying. I just avoid commenting on Souls as fans are really defensive about the grind. 

2nd Edit: Oops didn't even answer the thread question. Yes, critics should mention the difficulty level of the game. Also random difficultry spikes that are annoying in later half of the games. Ofcourse, whether it is positive or negative would depend on the end user.
