Also another thing: I don't doubt that certain reviewers are better at their "craft" than others. They may write better, they may be able to break down issues they have and explain them with great clarity, they may be able to see past their subjective biases and into what others might think of the game. But at the end of the day, people use reviews to either justify purchases or to back up their opinions about a game. On the former, I have found reviews to be wildly inconsistent, even from the same reviewer. This is normal because people like different things, and what one person enjoyed you wouldn't necessarily enjoy. On the latter, it's basically just selective data mining to prove your point on an internet forum.
In general I just don't see the benefit of reviews one way or the other. I enjoy reading/watching them as an informational piece about a game, but I would never make a purchasing decision based upon what is essentially another person's opinion.
