This is a justified score. It makes fair sense. Uncharted is far from perfect, and very overrated since it somehow became Sony's Mario label.
UC series constantly gets jeered by the same people who praise it. It's as off-balance as the games themselves. "Oh my god it's like the perfect game!!! It's so amazing!! I mean, there's like this one part with a jet ski...and another scene where the camera gets wonky...and another part where there's just frustrating waves of bullet sponges...but aside from all that 10/10!! I was super frustrated and irritated playing most of it but IT. WAS. EPIC."
That's the majority of people's thoughts. I've never agreed with that. These games are 6-8/10. For every good they accompany a bad. It's refreshing to see a reviewer give a score that's not pandering or obsequious.
