Even though I liked her as Miss Ellie trying to recast someone else in Barbara Bel Geddes' role just wasn't going to work.
Having Donna as her sister would certainly have worked.
I think Donna Reed is underrated as Miss Ellie. If she had been a carbon copy, she would have had negative reviews.
I appreciate that she at least dressed like a wealthy woman, and tried to put her own stamp on the character.
Granted, it was a difficult situation, but if BBG wasn't coming back (supposedly, Donna Reed had a 3 year contract)
Donna Reed could have added some more dimensions to her version of the character.
To each their own, I liked Donna Reed
