Re: BD's acting
It's really funny when Episode 4 (?) played up the acting inadequacies of Davis' daughter when she took over the role of the neighbor's daughter in WHATEVER HAPPENED TO BABY JANE?....though honestly, I never watched the real movie and thought, "Gee, that's one stinkin' BAD actress!!"
Is her actual performance actually bad? It's kind of a nothing part. It's not like she SHINES in it...but she's not really awful, either. (I realize that's faint praise!)
I'd pretty much just classify her as neutral.
