I like rating systems from -2 to +2 for this reason.
The big rating problem I have is with sites like boardgamegeek where ratings are treated by different people as either an objective rating of how good the game is within its category, or subjectively how much they like (or approve of) the game. They're two very different things and it makes the ratings much less useful than they could be.
They also suffer a similar problem in that most games score 7 out of 10. 8 is exceptional, 6 is bad, and 5 is disastrous.
