To me, the point rating is less important than the reviews within. If you can find games that match your style, then the point ratings don't matter as much.
Certain games that I don't like because they don't match the style of game that I do like - LOTR comes to mind - I can get that out of the people who leave detailed reviews. I really enjoy short, fast games. LOTR is a great game, maybe one of the best of all time... but it just doesn't mesh with my own personal playstyle.
