Yes. While trademark law prevents you from using someone else’s trademark to sell your competing products (you can’t make and sell your own “Rolex” watches or name your blog “Newsweek”), it doesn’t stop you from using the trademark to refer to the trademark owner or its products (offering repair services for Rolex watches or criticizing Newsweek’s editorial decisions).
That kind of use, known as “nominative fair use,” is permitted if using the trademark is necessary to identify the products, services, or company you’re talking about, and you don’t use the mark to suggest the company endorses you. In general, this means you can use the company name in your review so people know which company or product you’re complaining about. You can even use the trademark in a domain name (like walmartsucks.com), so long as it’s clear that you’re not claiming to be or speak for the company.
Since trademark law is designed to protect against consumer confusion, non-commercial uses are even more likely to be fair. Be aware that advertising may give a “commercial” character to your site, and some courts have even gone so far as to say that links to commercial sites makes a site commercial. (See PETA v. Doughney)
