Tonal Succession
Switching to a clearly different look and mood from one part to the next, either between chapters of 1 film or between a film and its sequel.
Avatar: The Way of Water
The first film was a green forest and this one is a bright blue sea. The look, the pacing and the mood shift with the setting. Each film feels like its own chapter in a larger story.
Avatar: Fire and Ash
After the blue sea of the last film, this one moves into a world of volcanic ash and fire. Cameron said fire refers to anger, hatred and violence, and ash to grief and loss. The look and mood shift with the characters' pain.
