A new take on the old having-an-affair-with-your-wife concept.

"Big Love" took a good turn last night. (Spoilers ahead.) We see that Bill Henrickson lusts after monogamy. With his Viagra supply deleted, he feels real attraction to Barbara, the only wife who was once an only wife. This favored love violates the system of morality the polygamous family has adopted for itself. The married lovers must tryst in a hotel or a car, the sex heated up by the fear of discovery and the knowledge that it's wrong. And yet it's not wrong, this monogamy, in the context of the larger society that is, in fact, about to discover the polygamy and ruin poor Bill. Meanwhile, the other two wives are going to find out about the monogamy in their midst and take revenge. What a complicated and exquisite dramatic conflict!
