why don't we call it jazz?

We call it jazz if they have got riotous, airy, dense, independent, united, spontaneous, courageous, absurd, rash, cinematic, acid, plural, spread, dizzy touch of feeling. Flavor of it up to 30s.

Hawks, Lubitsch and Renoir are the top notch. Keaton, Cukor, Barnet, Rivette, Altman, Mccarey, Godard, Tati and others on the list.
