The events portrayed in the film "Mommy Dearest" were based on the actual book written by Joan Crawford's daughter, Christina. So, the best answer is "yes," even though the truth is that most films make changes so that the story can unfold and flow easier.
It would be better to regard the book as a daughter's recollection: meaning there may be certain accounts in it that do not convey the whole truth. It is easy for the writer not to focus on what she did but remain riveted on the bad things her mother did. There are always two sides to any relationship.

An example of a campy movie is The Rocky Horror Picture Show or Mommy Dearest. They're basically movies that people like because of the ridiculous factor. You could think of them like kitch or cheesy.
