I am working on a new site and big part of the content is going to be user generated reviews and ratings.

Up to this point my intention was not to display the individual user ratings but instead to aggregate the ratings and display only the aggregated result. Then in a different section on the page I was planning on displaying the individual user reviews for the specific event.

Another important feature of my design is that the rating isn't a simple five star rating eg.: it sucks or it rocks. Instead I am asking users to rate the event based on 7 different metrics. These metrics are neither good nor bad, it all depends on the users outlook. For example something that is loud or quite, some people may prefer louder events whereas other may prefer quieter ones. All seven metrics are distinct and cannot be summed together.

User can rate an event without reviewing but the users cannot review the event without rating it. So every review will have one rating associated with it.

Now I am questioning whether or not it would be worth while to display the rating with the review. The rating may provide some more insight into the user sentiment. Or, will adding more rating information become too confusing. It is also worth noting that in addition to the user rating I plan on providing and algorithmic rating based on data from the event.

What would be the optimal design? Typically user reviews have a review and a five star rating, is my breaking with that widely accepted design pattern going to cause problems, one in terms of user adoption or experience and two in terms of SEO benefit?
