It feels more like Disney is suffocating audiences and audiences are now more aware that disney has a type. they show up for anything but most are not going for quality.
I don't agree to this. many movies are kid friendly, they get pg 13 ratings but it does not mean it is interchangeable with being made for children in mind. MCU is made for children in mind, a thing Disney has confirmed to the point of even having spiderman tell Deadpool in one of his comics that comic movies should be made for children.
MCU is specifically made for children in mind, only reason their screenplay is always light hearted and their movies have little realism but in appearances and tone this is what attracts kids naturally. Every mcu movie this year is a movie that is more a fitted for children's market.
Scorsese's Hugo has a more adult appeal than MCU movies because the script of the film is actually compelling and is not reliant of colourful CGI.
Personally think 4 movies a year is a bad idea, it could be a good thing if all the 4 movies look and feel different from eachother. I don't think it will happen because as of now mcu has mastermind the craft of specifics and a type.Also your right they dont have a right to dominate but they also dont have an obligation to make room for other movies. If people want more they are gonna give them more. They announced more release dates and looks like starting in 2023 we are gonna be getting 4 movies a year plus all the Disney+ stuff. So there is no signs of slowing down anytime soon.
