Why the particular example? I'm talking about metacritic average here : major Nintendo exclusives always get the highest scores despite being one generation behind, whereas top PS or multiplatform games are hammered at the first drawback. And it so happens that Nintendo is boasting about Metascores. I daresay that it's rather strange.

Maybe because reviewers don't assess games solely on graphics?

Yes, but PS4/Vita games never get credits for having top graphics. 3DS games aren't penalised for having 10-year old graphics. That's not normal, gamers derserve the best tech and journalists deny that by being soft on Nintendo games.

Furthermore, gameplay, story, etc. are very subjective aspects and can be manipulated easily. 

I finished yesterday (a friend lend me his psn account), its garbage. It was hard for me beating it cause I kept falling sleep.

As that Kotaku's Editor-in-chief wanker Stephen Totilo once said in interview with TotalBiscuit. - game journalism is mostly boring, unlike the other, "real" journalism...so guess they need to stir some shit up for traffic.

Of course PS4/Vita don't get any credit for grapichs. PsVita is rightfully penalised for having worse graphics and resolution compared to top ipad air games. Ps4 is rightfully penalized for being inferior to PC games. I agree gamers should only ask for the best tech and stop buying those trivial consoles.

And what about paid reviews? The Last of US was far from perfect but the scores smells very fishy.

Do you mean cuz it wasnt open world? Cuz if I was looking for that I would have bought gta5. For the people looking what a game like the last of us, that game was near perfection, where you not to like those games you would still had liked it very much. Even the complains among haters was mainly that it was so linear and wanted open world games, that should tell you more how few flaws that game had.

Edit: And how many games build so much hype and actually delivered on the goods? Almost none.

Are you actually sayiing that a game should be judge primarily for its graphics? If so my good sir you really dont know video games.

Absolutely not, I'm just saying graphics shouldn't be ignored when putting scores.
