Its technical achievement is stupendous: 95 minutes, one shot. What it manages to say in that 95 minutes may be even greater as it manages to capture the ideas of life, existence, art, death, history being in the past, moving on, moving forward all within its images, camera movements, and dialogue between our unshown narrator and the man in black guide. It's a extraordinary film, one that deserves to rank amongst the greatest in cinema for its technical mastery which matches its grandiose representation of ideas. This is what great film/art is about.
