The review system has been updated. The descriptions are much better now than they were six months ago. I think the rating system is probably fine the way it is and improving upon it any further would be counterproductive, in my opinion.

What you, as a reader and as a reviewer, have to do is to use your judgement and assign a rating based upon how you enjoyed the story. If you thought the story you read was superb and couldn't be improved upon at all, then give it a 9 or 10. If you thought the story was great, but the author really needed a spellchecker, then rate it slightly lower. So forth and so on...

It is perfectly possible to write a poor review and be nice about it. Many people here do it all the time. If we can get boccaccio out of hiding, I'm sure he'll agree.
