To be honest, I only consider that preview to be "negative" to those who can't handle any sort of criticism towards the game. Those who expect a (near-perfect) game.
Everything he wrote sounds fair and rational. Whether I'll end up feeling the same way after playing the game is yet to be determined. It's a good preview.
People need to lighten up.
Edit: the same, but in the other direction, is aimed at those who are jumping on any tidbit that's critical or negative towards the game and sharing it on all sites and Twitter in a passive-aggressive manner. It's sad to get enjoyment out of a game potentially being worse than what fans hope for it to be.
