I like that idea, then the developers would be able to know what they need to improve on. As for the AP, there could be the normal overall rating that you get two points for, and then once you vote on that a drop down menu comes out asking for your specific ratings that you wouldn't get AP for.
If your writing those 5 things you might as well put a little bit more effort and make a merit worthy comment. Some people just don't want to write a tad lengthy comment they just want to say "good game" or "boring".
People get points for just clicking a button? Wth?? I like how a more-specific rating system would define a game to a fuller extent, but people should NOT get points for rating it. Defeats the purpose of showing how good/bad the game is; the games would have a more legit rating given if people weren't given an incentive to rating it, because, like people have already said, they wouldn't give 2 cares.
