In case you missed it on Bravo, Moore’s politically charged series skewers greedy corporations, the NRA, ”compassionate Conservatism,” death-penalty-loving Texans, antiabortion ”terrorists,” Newt Gingrich, and many other deserving targets with the biting sarcasm and unabashed liberalism we’ve come to expect from the guy who made ”Roger & Me.” At times, Moore’s tone becomes strident, and the frequent use of ambush journalism almost makes one feel sorry for the politicians and corporate shills caught off guard by Truth’s cameras. But the writer-director-star gets his points across, usually in entertaining style.
