Is it safe to say that Joan Crawford was a malignant narcissist?

Oh yeah!

Absolute perfect textbook case of Narcissistic Personality Disorder. They ought to show "Queen Bee" in Abnormal Psychology classes.

It might be safe to say if anything in this movie or the ridiculous book of lies it was based on were true. The Joan Crawford character presented in the movie is a cartoon character who bears little resemblance to the real woman.
