Writers are often paid by their publishers to review video games. Rarely is a commercial review (those which appear in magazines and websites) written in the personal opinion of the writer. If you really think reviews should represent a balanced general opinion of the product then you must be naive. Some people write for a living. It's not bribery, it's a career.
Zero Punctuation is an awful, unjustified and biased video game review show that serves as comedy at best.
