Claiming that attempting to appeal to the “masses” is the same as aiming for the "lowest common denominator" is extremely elitist.

In the example of SheevTalks, he deconstructs and analyzes corporatized nerd properties like Star Wars, but there’s an underlying understanding that the failure of modern nerd works is that capitalism is inherently incapable of producing artistic works without turning said works into lowest common denominator commodities.

There is zero difference between this and Nietszche’s criticism of culture/art and modern society.
