Good v. Important

Stephen King is a fun read, but doesn’t exactly write for the ages. Salman Rushdie is an important figure for free expression, but not exactly reader-friendly. “Good” and “important” are supposed to go hand in hand, but often don’t. In books, film and the arts in general, what’s another pairing of a work or an artist who’s good-but-not-important with one who’s important-but-not-good? Don’t overthink the definitions of “good” and “important.”
