“In American Dreamz, a comedy about a faltering American president, a wildly popular TV talent show and the Svengalis behind them both, the jokes don’t just fizzle into insignificance; they flop about with gaudy ineffectualness, gasping for air like newly landed trout. Unlike fish, alas, gags about nitwit com- manders in chief, oily television hosts and rabidly ambitious young performers with stars in their eyes and sometimes their beds can’t be tossed back in the water; only a blunt instrument, like a hammer, will do. Consider this a hammer, humanely but firmly applied.” — Manohla Dargis in Friday’s [4.21] N.Y. Times
