You can tell that the navigation for SSMR was created by someone who has already read every review of every movie that is on the site. It's designed with the assumption that a visitor already knows exactly what movie they want to go to.
I realized that I have been neglecting the new visitor who comes to the site brand new and wants to catch up on some of the archives. So I've added a new navigation feature that makes it much easier to go through the site. When you are looking at a movie detail page, there are new links added below the movie poster (circled in purple in the accompanying image).
The next and prev links allow you to jump immediately to the next and previous movies, respectively. The movies are ordered alphabetically by title.
