The ending of La La Land is one of the most debated and discussed aspects of the film. There are a few different interpretations of what the final scene means, but the most common interpretation is that it symbolizes the characters sacrificing their relationship in order to pursue their dreams. This is supported by the fact that the scene is set at an airport, which is often seen as a symbol of new beginnings or leaving something behind.
Some people believe that the final scene is actually a dream, and that the characters never actually meet in real life. This interpretation is supported by the fact that the scene is very dream-like and surreal, with the characters dancing in the rain and the sun setting in the background.
Whatever the interpretation, the final scene of La La Land is certainly open to interpretation and has sparked a lot of discussion among fans of the film.
