I read the books many, many years ago - actually weigh before I watched the full run of the series which was impossible for me at that time.
I can't remember too many details of that book series. But I remember one chapter about Jordan Lee and Kristen making love, which was really hot for me back then.
The description of Miss Ellie is really interesting. Larry Hagman always credited his wife Maj for his decision to join Dallas. He had a few scripts to choose from. Maj adviced Dallas because "there is not one nice person in the script."
I'm pretty sure the early draft for Miss Ellie was far more multi layered than what we got. But as many characters changed in the early days of the series (more Sue Ellen for example) and JR becoming the star of the series - it probably had its effect on Miss Ellie as well.
Although I can't remember too much, I do remember that I enjoyed it. I hope you do as well.
