User Contributed Rating System

I am working on developing a user contributed rating website, much like rottentomatoes.com in a lot of aspects.开发者_开发知识库 Are there any open source content management systems that I can use as the foundation of what I am building?

Thanks!!

You could try Wordpress with some plugins like http://wordpress.org/extend/plugins/comment-rating/. Then, for every movie/book/game/whatever, you can make a new post, and people will be able to review it. You can just leave the homepage and it will display that newest additions, or you can make it display a static page too.
