I disagree that Dorian Grey would have been improved with length. Oscar Wilde was a particular writer and his length was a choice that highlights his aesthetic ideals.

While I can think of many books which would be improved with editing it down, I'm not sure I can think of one that needed more length. Often the lack of clarity and high specificity of word choice in shorter stories serves a specific purpose.

I never said Dorian Gray would have been better if it was longer though

Huh. When I read Dorian Gray, I kept thinking, “I wish this had been a short story!”

I tend to think exactly the reverse. I'm always trying to figure out what's the fewest number of words that can tell this story.

I could have went for more of The Stranger

I agree with you about Dorian Gray.

Also, Pachinko by Min Jin Lee probably could have been twice as long, and I still would have loved it.
