What's funny/sad is that if you read the reviews of the high scores, there's little in those reviews to justify the high score.
In fact, in most of the reviews, it sounds like they're talking about a very mediocre (read: 5 or 6 out of 10 range) game instead of a good (7/8) or great (8-10) game (and yes, I'm painting with a broad brush here). This game is being damned with such faint praise, it would take the entirety of the Catholic church to pray it out of hell, and even then, it would only ascend to Purgatory.
And this is more an indictment on games journalism and how lacking in Ethos the industry has become more than anything else. Fanboys are gonna fanboy--you can use logic and reason with them, but they're still going to believe the Emperor's clothes are fantastic while the rest of us see that Kojima is a grower instead of a shower.
¯\_(ツ)_/¯
