Although I'm only going by the same sources that you are (alas), I think I can safely second your impression, though I'd disagree with your use of the terms 'warped' and 'perverted' to describe one's appreciation of Edna's obvious assets.
In fact, I'd say an attractive female lead is an important element of Charlie's films. Say what you will about Charlie, he had a good eye for signing attractive females to play against (um, so to speak).
In contrast, with the very notable exception of Marceline Day in 'The Cameraman,' I find most of Buster Keaton's leading ladies to be notably less appealing than Charlie's.
And nobody throw back the names Martha Raye, Phyllis Allen or (shudden) Marie Dressley... please!

P.S. - And, Connie - thank you, thank you! The package came.
