All I'm going to say if the same type of preview was perhaps written at RPS about Dark Souls II or another "loved by NeoGAF" game, it wouldn't have gotten such a negative reception than a sequel to a game that a certain segment of neoGAF hates for whatever reason, especially since it came from the ESPN of gaming sites.
All this is basically, your opinion. You wanted to know more about the game, he chose to write about his experience with the game. And honestly, a lot of people want to hear about how awesome the game makes you feel, not indepth explanation of every nook 'n' cranny. If that isn't what you want, great. But, that doesn't make it "bad" simply because you disagree with the writing choice somebody made.
Maybe there isn't anything blatantly wrong with the game in the writer's eyes? Again, I understand to a certain segment of neoGAF, if you work in the enthusiast press and aren't completely 100% cynical about every major AAA release, you're bought off, know nothing about gaming, or whatever the latest slam of the week is, but I find it completely possible than in his 4 hour session, the writer found nothing wrong with the game.
