Reviewer

From Conservapedia

A reviewer is someone who analyzes and judges a work of art or entertainment and presents their opinions to their audience via print, television, or the internet.

A talented reviewer can help the potential consumer tell whether they would enjoy the work or not regardless of whether the reviewer liked it or not.

Reviewers sometimes include a great deal of background information about the subject involved, or biographical information about its creator, making some kinds of reviews an art form of their own.
