Unless you click further, which few actually do, they do not show you the complete ratings. They only show you ratings of those who bought movie tickets in a certain fashion. In addition, it is thought that they artificially change ratings by removing ratings.

The expert reviews are very biased here compared to other sites like IMBD. It is quite often to see a movie get nearly full marks as an expert, but a rotten score from the users, and vice versa. This is almost always political, such as if it is a feminist movie (see reviews for Taking Down the House, versus Chapelle's Sticks and Stones).
