Like others above I think it was well acted, and yes it was entertaining, but it also left me feeling we hadn't addressed the core issue - which, because it's not a documentary, is not sex, but the development of the character. There was nobody who challenged him about his obsessive behaviour (workaholic), even his clearly intelligent wife just let him steamroller ahead, jeopardizing the family, his health etc.
All the nature films I've seen on TV have the naturalists (no I don't mean nudists) get all excited about courtship rituals and dances between animals. Peacocks spreading their plume, birdsong, emission of scents etc. And yet when Kinsey goes into a gay bar with his macho determined manner and gets the cold shoulder and acid comments from the gays, doesn't it occur to him that this too is part of the game, the affirmation of differentness, the prelude to the act? For me he focused too manically on the sexual act. But hey, it was groundbreaking research, I'll give him that.
PS I remember reading somewhere the film is not actually a reliable biopic.
Richard2, did you see the same film I saw? I respectfully offer this:
Regarding his workaholic behaviour: The movie's already 2 hours long and doesn't need a long, drawn out scene depicting Mrs Kinsey's concerns. She does express it, however, in the scene where the Kinsey's are being swarmed by the press: she says "My husband's busier than ever. I hardly see him since he's taken up sex." Later, he collpases giving a speech. At the hospital she says "He's killing himself."
Regarding his macho, determined manner: He's the son of a self-righteous, uptight, judgmental preacher. Change is hard. Nuff said.
Regarding the development of his character: He expresses his (unfounded) disappointment that he couldn't help people. Later, Lynn Redgrave thanks him for changing her life, and the entire world.
