World's Greatest Dad (R, 2009)

Director Bobcat Goldthwait loves exploring the consequences of shocking personal controversies. His earlier indie comdie, Sleeping Dogs Lie, chronicles what happens after a woman confesses a past sexual indiscretion involving her dog to her fiance. Having covered bestiality, in WORLD'S GREATEST DAD, Goldthwait moves on to autoerotic asphyxiation, suicide, and a frustrated man's desperate need for fame and notoriety. Once the initial shock at young Kyle's (Daryl Sabara) utter unlikability wears off, the movie settles awkwardly into a more traditional black comedy mode, focusing on Lance's unlikely rise to fame.

Williams, who's known for his grandiose performances, thankfully keeps Lance understated. It's almost understandable, at first, why Lance covers up the real cause of his son's death, but once he starts cashing in on Kyle's posthumous popularity, he loses the audience's goodwill. Sabara, ages away from his adorable Spy Kids role, is scarily good at being a sick puppy of a teenager. And as Lance's foil, Henry Simmons is perfectly cast as the kind of attractive man who's a magnet for success and women. Goldthwait has a knack for exposing ugly truths, but it's a shame that so much of World's Greatest Dad is nearly unpalatable before those truths are revealed.
