Gerstmann rated it low as well, and he's an icon of honesty and integrity in gaming journalism. At least that's what people claim when ripping on Gamespot reviews these days.
The dude's Kane & Lynch video review (the one that got him fired) didn't even show anything past the 10 minute tutorial level actually.
Truth. He should've been fired for not doing his fucking job. That review was packed with innacuracies, it was really clear that he didn't play the thing to start with. Gamespot made it worse and I like Giantbomb just fine, but to act like the guy is the fucking Joseph Pulitzer of the format is ridiculous.
