Hollywood no longer has movie stars that can singularly carry a new IP.
Hollywood's star system allowed for new IPs to be created.
Hollywood's transition to the franchise model means that movie stars like Robert Downey Jr. are tied to a franchise indefinitely because there are no movies that will pay him 30 million and there are hardly any IPs being created worth making due to costs and return on profit...since y'all motherfuckers don't watch anything new and stuck on nostalgia and geek shit.
So, directors don't matter. Screenwriters don't matter. Movie stars don't matter. Only franchises and IPs with exploitable fanbases matter.
Any and every up and coming star director, actor or screenwriter gets funnelled into franchise bullshit which ruins their individuality and ability to draw audiences to new IP. And the current ones are vultures, trying to cash out as much as possible.
