If the game review is below a 7 and I don't know the game I don't read the review. If the game is 8.5 or above I read the entire review unless it becomes clear I don't like that kind of game.
Generally I go to the big 4 IGN, 1UP, Gamespot, and Gametrailers. I usually read or watch (Watch if possible) their review and then make a decision based on the aggrigate. When the concensus is that a game is good I buy it almost without exception. If there is variance in the scores then I base a purchase off how much I like that genre and what specific reviewers liked or disliked.
I am a story whore for example, so a game with a poor story and great gameplay still won't win me over easily. Really I don't see why people make a big deal of numerical scores, if you're interested in the game you should want to read about it. If you don't that's fine, but you can't really complain if you end up hating it.
