The main points of debate include whether the abuse stories were true or exaggerated. Also, people question if Joan Crawford's supposed obsessive - compulsive behaviors were accurately represented. And there's debate about the overall tone of the portrayal - was it a fair representation of their relationship or a one - sided smear campaign? The movie seemed to paint Joan in a very bad light, but some think there might have been more to the story and that Christina might have had her own motives in presenting things the way she did in the memoir.
One main point is the severity of Joan Crawford's behavior. Was she really as cruel as depicted? Another is the authenticity of specific incidents like the way she treated Christina during her upbringing.
