Well there review seems fine as, aside from the dialogue which has been a concern from many, but the main concern for them has been controls. And if the reviewers isn't digging the controls then obviously they aren't going to give it a stunning review. Now a lot of other reviews I've gone over seem to completely disagree with that aspect, but can't question them for their review when it seems justified by them not liking the controls.
As for the integrity of GI and there ability to take neutral stances on all games they review... no comment.
