Probably shouldn't be. Although Blonde is admittedly fiction it kind of takes a Darkest Timeline approach to her life and shows just how rough patches of it could have been. And that version of her certainly suffered terribly.

She's good as an example, though. If anything. For modern people to look at the scum involved in her life, who used and abused her, and to identify and recognize if anyone in their lives behave similarly, gaslight them or manipulate them. Maybe knowing how to spot that sort of thing ahead of time can save someone else.
