Now that you understand the language the Letterboxd Community uses and you have created an account, what do you say? It can be intimidating to start writing your own reviews, however there are many different ways you are able to approach this.
Many people who use Letterboxd will make humorous reviews about movies; these reviews take themselves much less seriously and often praise very lack luster elements making silly movies seem like Oscar winning titles.
Another sort of review that Letterboxd users will recognize are on the more serious side. These reviews will discuss character development or lack there-of in a movie as well as pacing, themes, and the overall meaning. These reviews are perfect for Letterboxd because it is up to the viewers interpretation to decide what the movie does well and where it falls short!
Another very common example of what to say in the Letterboxd Community is breaking down the making of the film itself. Many people enjoy talking about how lighting was used well, what different camera shots provided to the story, and sometimes even throw in what they think could make it better. Discussing the technicalities of a film is great and really shows your interest in the subject, even if you're not a professional!
What is important to remember is that whatever YOU as the viewer want to write and feel compelled to share, you are allowed to do so as long as it remains within the community guidelines!
