I don't think it is a misnomer in the way I was using it ...
When I watched 'Count of Monte Cristo' recently with Depardieu as Edmund Dantes, this French movie wrote in a girl friend for Dantes and he got together with Mercedes in the end. This total rearrangement of the story ruined the movie for me. Many Hollywood movies totally change the action. It is like the screen writers are thinking nobody has ever read this book, so let's do this.
If you saw the Masterpiece Theatre 'The Last of the Mohicans"; then you watched the Daniel Day Lewis Hollywood version, you would swear they were two different stories. The latter wasn't a bad movie, but for me, totally aware of Fenimore Cooper's works, it was a mish mash.
It is even worse when Hollywood changes history. It's bad enough when they rewrite fiction, but when they change historical facts or chronology, it's terrible.
