To add more to the discussion, I don't necessarily feel that it's large-website homogenization that's the problem here. In recent years IGN has really been pushing video/audio content over written content. Written reviews have also gotten noticeably shorter, no doubt because they ran some numbers and figured most people don't actually read them beyond a certain length so why bother. But I think the biggest problem is that they really want to be an internet TV channel or something, with video news, video reviews, video editorials, etc. There is much less emphasis on the written word these days. Personally I hate video content because I can't just skim it and pick out the parts I care about, but I guess I'm in the minority.
P.S.: I don't give a shit about their score. That was never my complaint.
