The opening-night film comes to Sundance with the kind of publicity for which Harvey Weinstein would pay dearly. However, Lauren Greenfield’s genius move lay not in PR strategy but in her choice of subject. David Siegel’s the kind of guy who not only thinks it’s sensible to build a 90,000-square-foot mansion (just before the real estate bubble burst, as it happens), but also thinks it’s a good idea to file a lawsuit threatening Greenfield and Sundance the week before the film premieres, complaining that the movie makes him look bad. (Never mind that the attendant press attention and public record about his $11 million foreclosure in May 2011, serves to make him look… well, bad.) All that aside, Greenfield also has an eye for candy-colored disaster that is never anything less than incisive and entertaining.
