My videography professor showed us this film in school. It was a brilliant example used to teach the minimalist approach to filmmaking and how if you can do that, you can do anything with a camera.
I have seen better acting in high school plays. Steven Wright is already playing a role, his persona. Steven Wright doesn't smoke, and it shows. Steven Wright is not an actor. I have seen children fake-sicking to avoid school achieve more realistic faux symptoms than Roberto Benigni's hand tremors. That addresses the on-screen elements, let's talk director. Sound was poor, staging was poor, framing was weak. No music, no ambient sounds. No narrative. This is the Q-anon of film. Ambiguous and meaningless while pretending to be something deep. Garbage.
