There's enough room on TV to experiment and create real art. Movies are a commodity that have to make money which is why the stories are all recycled comic book trash.
Partly true, but its really not quite like this.
Television is really structured, theres nothing really experimental about it. On films you can have a single camera and way more time to create shots through ‘pre vis’ and storyboarding, get arty and push the envelope with angles etc. You film a minute or two per day on films (one page of script usually = one day filming), and between 5 - 8 pages on TV.
TV is usually a two camera set up, and that affects the lighting. Its ALL about lighting. TV shows typically have multiple Directors and the first is the ‘set up’ Director. The showrunners or producers set the tone. Its up to TV Directors to get enough coverage by how many set ups (they do 3 or 4 setups = 6 to 8 different angles of the same scene) where films can do 1 shot.
You’re right in that movies are a commodity that have to make money, and TV shows are usually pre-sold and have strict budgets, but a film can take shape as your shooting it, and it can attract more investment based on the results, where TV is a set figure that is much more a product.
I havent read the story but I reckon its the diversity of scripts and characters that are drying up, just like music. Films are just not as controversal or revolutionary as its evolved over time, and now everyones a filmmaker and its not exclusive to make films anymore. The reliance on tentpole films to fund the diversity within filmmaking isnt new, but the audiences are hyper critical and prone to way more extreme and smarter views. Filmmakers are absolutely terrified of you, and would rather play it safe so they get another job next time.
Step out of line and they get publicly murdered.
