What is the author's style in Sculpting in Time: Reflections on the Cinema by Andrey Tarkovsky?

Tarkovsky relies on his theoretical understanding of film, as well as his practical experience with working and directing on many film sets. He supports his ideas on the essence of art and cinema with examples from his own career as well as artists and works he admires. He shows himself to be forever curious and ever-evolving in terms of his films. Tarkovsky admits that Ivan's Childhood was the result of experimenting with different techniques. At that point, Tarkovsky was still determining whether or not he had the desire and talent to become a director.
