No matter how many things you pick out that can be looked at it an objective fashion, the end result is going to be whether the reviewer liked something, which is very subjective.
True, but most places tend to put reviewers on the Genre's they are most familiar with, so someone reviewing KZ would usually be familiar with all the latest shooters, and with their somewhat expert opinion, should be able to give a fairly accurate rating of how the game compares to it's contemporaries.
I really don't think it's that subjective, generally most reviewers all rate within the same 1-2pt range for a given title, title's that are truly great tend to get consistent 8.5+ everywhere.
That goes doubly for a first person shooter. I can't think of a genre that could be measured more objectively than FPS, just because there are so many, and the mechanics are so extremely similar in each iteration.
All that said, these reviews are very strange. Is this game any good or not!? I had high hopes before launch, then decided not to buy it, mainly because of the Polygon review, 5/10 basically means "This game is shit", then GameTrailers throws down an 8.8? Huh.
