Just posting this, cos I think u ppl are kinda not looking at the best solution: SPLASH' idea.

Splitting the rating into a reviewers rating and staff rating. People can compare the different ratings and get a more detailed, neutral point of view. There are major review sites on the net which use such a rating system. If u go to http://www.gamespot.com u'll see such a review system is used there.

Looking at this topic, all the top reviewers here are asking for a system which lets them have more effect on the final score of a download. This would be totally inconvenient, since people who would just sign up as new reviewers could posses incredible review abilities. This way their voice counts less than so called 'higher' ranked persons.

Not only that but the coding of a splitted review would be much easier. U'll need some respected and good reviewing persons as staff, around 5 or so, and yer done. When a lvl is rated 7 by the staff, but has a 9.1 from the users; people will start thinking and see what's the cause of the difference. For example the lvl has only been rated by his pals or someone was pretty new to the system.
