France already has writers, producers, distributors and vertical experiments. The complete, sourced analysis is published on Streaming Lens, in French.
Vertical is a container. Melodrama is only what was poured into it first. France's question is not whether it can shoot in 9:16, but whether it can connect writing, production, distribution and measurement often enough for industrial learning to appear.
The Streaming Radar corpus already shows the French pieces. The full analysis maps them.
The Lens page draws on SR #37, the Hugo Brisbois interview, Gilles Daniel, Guillaume Sanjorge, SR #53 and SR #54.
