Publish your commentary. If film criticism is a hobby, you might be happy publishing your work on your film blog alone. However, if you are trying to become a professional film critic, you should send your work to newspapers, magazines, and online publications to try your hand at getting published. While jobs with print media are becoming more scarce, digital media offers a wide range of new opportunities. Getting published is difficult, so don’t give up! It may take years of practice, so keep blogging, reading the work of other film critics, and studying film.
