Review scores in the 7th gen have been severely inflated, I'm shocked at the scores certain games received, especially games with crucial flaws and/or poor design choices. Some games that are into the high 80's and even 90's have mindblowing faults and issues, many reviewers seem to let them pass since they have redeeming features, it's just not balanced and I often find myself wondering if the final score is actually related to the text of the review in those cases where they actually write up about these flaws. I've seen reviews that have 70% negative text and then end up giving a 9/10, it's ridiculous.
To me, this is sort of like a really hot and dumb woman having a speech for a bunch of horny men; they will walk away feeling good despite the fact that she wasn't really a good orator and they will focus on the wrong things. There you go; a slightly mysogynistic analog to enjoy... 
That said; in my honest opinion, The Last of Us deserves a lot more than a 6/10, it was actually one of the best game I played in the 7th gen overall. The video is still awesome though!
