It's really quite simple.
The hatred is due to some of us loving the Gentle Doctor's original works, which the title of the film refers to and the film itself craps all over. If you find the film's alterations "very intelligent" - I weep for you.
As for the Foundation trilogy - while I'll grant there aren't a lot of female characters, claiming "none" proves your ignorance of the work; I'll mention just two: Bayta Darell, and her granddaughter Arcadia ("Arkady") Darell. Neither are wilting flowers - in fact, Bayta is instrumental in the defeat of The Mule.
