"Don't bother to watch this film" would be better advice, if you like Marilyn Monroe in her other roles. This was a huge disappointment considering the great cast, not just Marilyn.
The story was just nothing, certainly nothing like described on the VHS box, of course. There simply was no suspense, precious little excitement and too many dull spots, most of them trying to show why "Nellie" (Monroe) was so messed up. This was not a good role for Monroe, even though I didn't need to see this character to know she could act. "Some Like It Hot" alone was good enough evidence for me. But this role just didn't fit her and it's no surprise it wasn't one of her more popular films.
It's also too bad a film had the waste of the talents of actors like Richard Widmark, Anne Bancroft, Elisha Cook Jr., Jeanne Cagney, Donna Cocoran and others.
Summary: it's not entertaining and entertainment is the name of the game.
