Tonight marks the series finale of Big Love, a series about Mormon polygamy centering on Bill Henrickson and his three wives, who are attempting to be the modern, humane face of polygamy against the long, dark shadow fundamentalist shadow cast by Juniper Creek, the polygamous compound where Bill grew up.Sometimes annoying, sometimes over-the-top, the show nonetheless kept my interest during its five seasons, in part because of the superb acting. I have no sympathy for polygamy. But in spite of myself, I ended up having sympathy for these fictional polygamists. In addition, it is one of the few shows on television that takes seriously the attempt of people to live their faith, with hope and courage.I'll say more about it after I've seen the finale. But first I want to go on record with a prediction (and no, I don't have any inside information.) I predict that Bill will receive a vision from God or one of God's Mormon prophets, telling him that feminism and polygamy are compatible, and that he and Barb (his first wife) must together found a new church that integrates the two. Priesthood holders do not have to be men; Barb and he will be priesthood holders together.The writers want to go out with a bang. A brand-new divine revelation, well, that's a bang.Am I right? I'll let you know tomorrow. Or watch yourself, on HBO at 9 p.m. (Eastern Daylight Time).
