Lisa Jane Persky may be a terrific human being and a competent actress, but there is no way of believing that she sprung from the loins of WASP Goddess Blythe Danner . . . . and, no, I don't care how much of Robert Duvall's splooge reached her uterus.
It's called heredity, CSA (Casting Society of America) members!
