I usually look for player reviews who ARE NOT affiliated with a major company. I find that reviewers who review a large amount of games (Like Yahtzee, for example) tend to become much more biting towards games when they normally wouldn't.
They may bring up good points on the bad aspects, but they seem to become so influenced by so many other games, that the inevitable, though at times minor similarities between games become a nail in the coffin for said game.
