It is speculative at this point how much of this is true or "gamer" beliefs. what its true its that there are definetly trash bait reviews. 

What is true as well is that there are games that surpass the 95 mark still to this day.

according to Metacritic, there are 10 games from the last decade that are 95+

Portal 2, Red Dead Redemption,The Last Of Us,Skyrim,Mass Effect 2,Super Mario Odyssey,GTA V,Red Dead Redemption 2,Breath Of The Wild and Super Mario Galaxy 2.

being the last 5 of the metioned reaching as high as 97. 

So I don´t think gaming criticism is as broken as people like to say, it is just that hard to get an above 95. all of the games previously mentioned are legendary.
