<p>With war looming in Iraq, it's more crucial than ever to get cogent analysis of the country and its despotic leader, so what does Cinemax offer? Irony. Smarmy, smarmy irony. "Uncle Saddam," which airs Tuesday night on the cable station, gives viewers an exclusive look inside the palaces, museums and other edifices that Hussein maintains on Iraqi soil, and it also provides a time line of Hussein's life, from his troubled childhood to his post-Kuwait grip on power. Filmmaker Joel Soler does it with so much snideness and smugness, however, that his movie is almost unwatchable.</p>
