You can disagree, but I thought he stated clearly why he was disappointed. Maybe you are content with what the game offers, others aren't because they had an expectation that wasn't met.
To me this game feels like a strong argument of $20 at launch with expansions along the way. Asking $60 now with the promise of updates is hard for reviewers who need to get reviews out now instead of six months in the future. Right now it may be a 4/10 at $60, and it could be a 9/10 in a year at $20.
I never got getting worked up about reviews, if you're having fun, enjoy the game.
