In "The House of Yes" Posey plays a nut case who calls herself Jackie-O, dresses like Jacqueline Onassis, and likes to have incestuous liaisons with her brother while doing impromptu reenactments of the Kennedy assassination. A claustrophobic dark ensemble theatrical knock-off, this stagey flick relies on the nonstop repartee of its quirky characters for entertainment as it is devoid of just about everything we go to movies to see. People and talk is all you'll get with "The House of Yes" which squeaks by with a script just clever enough to shore up a marginal concept. Okay fodder for those into dark, sardonic, and misanthropic comedy. (B-)
