I don't know, you are bound to get a bit of inconsistency between reviews. I mean they are all supposed to adhere to the same rules and review everything by the same standards, but you can't expect everyone to share the same slightest preferences. I think Gspot like PCG are only two the few places that present a uniformed standard more than most.
We are talking about Gamespot, a website that for the most part does a great job of having its reviewers stick to a strict code. If anything, for my liking it is a bit too strict, and it keeps the personalities of some of the writers from shining. But it is their style, and despite the occasional straying, I can't think of anyone who does it better.
As for Doom 3, in retrospect, his review was spot on, though his score was probably a bit too high considering his complaints.
edit:
I did find his complaint about it being illogical for the marines to not have a 24/7 flashlight to be a bit retarded. I mean for me the game was all about atmosphere, and that atmosphere was triggered by two things; sound and lighting.
The best way for the claustrophobia and horror to really take effect was to have light be scarce. So they chose an illogical way to go about it, so what? It was a freakin' plot device.
