I was never a Miss Ellie fan (Not to be confused with BBG as an actress)
I would have preferred her to go to Knots Landing
so that I wouldn't have to listen to her insufferable self-righteous hypocrisy,
her tacit approval/enabling of all the unethical Ewing Oil dealings that
gave her a life of wealth and privilege, her ghastly parenting that largely
created JR's personality and her refusal to admit (for years) that she married Jock
to keep Southfork.
Also the story that she chased Jock and demanded he marry her -
In another context that could be stalking
When BBG left, I read one report that Dorothy Malone turned down the role.
That could have been interesting
While Donna Reed was not universally loved as Miss Ellie,
I think that sometimes it is overlooked that she was a well accomplished actress
She portrayed Mary Hatch Bailey in "It's a Wonderful Life", an all-time classic
She won an Academy award for Best Supporting Actress in "From Here to Eternity"
As the Star of "The Donna Reed Show" she was more assertive than most Tv moms
of that era, and she was nominated for The Emmy multiple times.
She had many other roles as well.
In an interview, I read that she wanted to base her Miss Ellie portrayal
on her familiarity with Oil Barons wives that she knew from Oklahoma,
and that she wanted to move the character away from always seeming
to hold a coffee cup.
I would acknowledge that she certainly dressed more like
a wealthy Oil Baron's wife.
Maybe if these aspects were prioritized more, we would have seen
a better viewer reaction.
In any case I would be all for moving Miss Ellie to KL
Others may disagree with my analysis and that's fine.
Maybe BBG needed better writing for the character
If she moved to KL, my response would be good riddance.
