I don't tend to seek this stuff out, so I may just be seeing the stuff that's dumb enough to be notable, but I find the way the popular games media talks about Final Fantasy XIII more often than not embarrassingly snarky, hyperbolic, uninformed and one-sided.
"The other games weren't linear", "lol feathered hair, "Nomura ruined everything!", "anime melodrama!", "20 hour tutorial!" or "oh, Japan!" aren't valid criticisms in and of themselves. They're not invalid, but they're not established facts that don't require any support. The "I'm an old-school FF fan" angle reads to me as idealized nostalgia, though in fairness I haven't played any of those games. FF VI could very well be the best game in the series, but if it was a formative game for someone, I doubt anything could really compare to the nostalgic reverence they have for it.
To put it more directly, if you're going to shit on something (or speak about in a condescending way) and your job mostly consists of writing, you should be able to put together a coherent argument to support your position. A large number of people saying a thing doesn't make it true.
(If this reads as bitter, it's a result of my just finishing XIII-2, finally watching the Lightning Returns trailers, and reading insufferable comment snark from the GB peanut gallery. Lightning Returns, by the way, looks pretty cool, and I didn't even have a lot of love for XIII-2.)
