Metacritic is an indicator but a blind trust in their score is stupid, it's not always reliable for example, Alien Isolation is way better than Shadow Of Mordor, but meaningless scores like IGN one because the game is too difficult just prevent the game to reach the score it deserves.
And about reviews in general, most of them have a big flaw making them useless for games with big updates, the journalist never updates the review. The last Gran Turismo is a good example of that.
Predictions for end of 2014 HW sales:
