There are some rather dumb people reviewing here saying "What's the big deal, you needed insemination from a stranger anyway?" When someone seeks artificial insemination, back then and now, they choose from a pool of donors who've been through health screening. Meaning anyone with a medical condition is forbidden from being a sperm donor.
This imbecile Cline is/was not a healthy man. He has/had auto immune disease. He wouldn't have even gotten through the first hoop of donor screening! So you see, there's a problem here. And this is just ONE of the issues with what he did. He co-created nearly 100 human beings that are now predisposed to becoming ill.
The film needed to be dramatic to get the message through to the public more effectively.
I'm not going to detail the rest of the issues related to his conduct, but this criminal needs an appropriate prison sentence, or be admitted to an asylum. One, to assist his victims to move into closure mode, and two, to set an example for other offenders who wish to violate women in this way.
