Bob Dylan is famous for his talent as a composer and musician. That's why there's a movie about him. His personal shit is just background. If we cancelled all the musicians, composers, actors, painters, sculptors, writers, and other artists who sinned in their personal lives, we'd be left with Mr. Rogers. Forget about all that shit and concentrate on the talent that made them interesting.
