What I did was make a review entry page (or pages) and separate the different categories out -- different text box for each category and each labelled. So each category was a separate db field. Reviewers would just fiill out the form, assign a score to each category, and then submit it. It was up to them to fill out the content. Two sentences doesn't cut it :p , then I'd just page on the separate categories with a summary/final rating at the end.
