That's true. It's because middlebrow stuff has pretensions of being highbrow. Lowbrow stuff knows what it is.
I felt Joker was a middlebrow film, e.g. although I didn't judge it in those terms exactly.
kind of surprised that you say that with your knowledge of western classical music which is by and large based on very lowbrow peasant folk forms transposed to entertain the kings courts (and then later the bourgeoisie.) This is why Adorno venerated Schoenberg and not Stravinsky, which he thought was too tied to primitive nationalistic folk sentiments whereas schoenberg was a total avant-gardist making his music pure mathematical abstraction of the commodity with no feeling, the absence of feeling sort of becomes the feeling, as Photek said in the wire.
