Looking at Metacritic, I see lots of 10's that are blatant bumping the ratings. Copy pasted reviews for XBOX, PC, and PS3 from the same person giving it a 10.
From my brief time watching /v/ threads, there was no consensus, and they only voted negative to the blatant fanboys pumping 10.

This one is okay, he gives the XBOX a 9 without having played it, but at least it isnt blatant copy pasta, I would count that vote because he believes in the game.

Copypasta with an axe to grind vs XBOX release. Gave XBOX 2, and PC 10, with the same review.

Biodrone counter trolling a misconception that /v/ is doing it as a deliberate act.
So out of 28 ranks ot 10, we can see 7 with a copy pasted replay on other platforms, well, 6, one was kind enough to compose an entirely different review.
There are three 9's (four lights?), five 8's, two 7's, seven 6's, two 5's, nine 4's, fourteen 3's, twenty 2's, thirty two 1's and over fifty 0's.
Discounting the 10's and 0-3 score, you arrive at an average of 6.035 (many more numbers after this) If you drop the 4's, you get an average of 7, and 7.235(more numbers) if you drop the 5 and below and do not count the 10's.
This is the user scores however, so take it as you see it, but scoring so low on metacritic even by removing the extremes, and even if I were to add half of the 10's as a legitimate score, the results would be.
Ignoring half of the 10's, and 0-3 scores. 7.357
Ignoring half of the 10's and 0-4 = 8.2727
Ignoring half of the 10's and 0-5 = 8.766
Almost in line with the professional critics scores, and that is being generous with picking scores.
Then again, you can only really judge it for yourself after playing it 7 times.
Edit: also, a statistician would hang me for this, its awful to read.
