I'd like a rating system that intelligently weighs the reviewers and provides the overall grade after adjusting for individual review points.

Examples:

- if a person only posts 5-star or 1-star reviews, they are polarised and/or punitive. Any and all reviews from such users should be weighted accordingly - 5 stars clearly means "thumbs up, for whatever reason" and accordingly 1 star means "thumbs down, for whatever reason".

- if a person posts a fair selection of review scores, they are likely more thoughtful. Individual review scores from these users are more accurate.

- if a person posts mostly 2/3/4-star reviews, then any 1/5 star review is likely to carry a lot more weight.

To make score manipulation slightly harder, some kind of meta moderation would need to be in place too. Preferably on a per-category basis, so your reviews might have "good karma" on some topics and "bad karma" on others.
