Art criticism, I would say, is about the most ungrateful form of 'elevated' writing I know of. It may also be one of the most challenging. . if only because so few people have done it well enough to be remembered. . but I'm not sure the challenge is worth it.
There are probably a couple of things I'd never write about until everyone I know is dead. And then there's other stuff which nobody would want to read a book about anyway.
