I think you are referring to Leni Reifenstahl, a very talented filmmaker who made propaganda gilmd for Hitler. No one can deny she was amazingly talented, but it’s not like she has a legacy as a filmmaker today. Even though many of the techniques she pioneered are still used in sports and elsewhere.
I was just using hyperbole to point out that sometimes a person’s off screen (i.e. REAL) persona is just so evil/bad/wicked that you can’t get that out of your mind when exposed to their stuff.
It’s why I got rid of all Barbra Streisand albums decades ago.
