What is the definition of the term ''existential cinema'' and what are some key principles and examples of the genre?

Existential cinema is a genre of film that focuses on themes of human existence, freedom, and the search for meaning in life. It often deals with topics such as mortality, isolation, and the struggle to find one's place in the world.

One key principle of existential cinema is the use of long, contemplative shots that allow the viewer to reflect on the characters' experiences and emotions. Another principle is the use of non-linear storytelling and ambiguous endings, which encourage the audience to engage with the film on a deeper level.

Some examples of existential cinema include Ingmar Bergman's Persona, Michelangelo Antonioni's L'Avventura, and Stanley Kubrick's 2001: A Space Odyssey. These films all explore the themes of human existence and the search for meaning in their own unique ways.
