The biggest laugh Watchmen got at the sold-out, 9 a.m., IMAX suburban-theater show I went to on Saturday occurred [SOMETHING OF A SPOILER ALERT HERE -- LOOK AWAY IF YOU MUST!] when the Lee Iacocca-businessman-figure said, "Free is just another word for socialist." It was the happily derisive laugh of a crowd that was totally into the movie, and which also seemed well aware of the recent effort to label the Obama stimulus package as "socialist" -- and the audience clearly thought the use of that supposedly-inflammatory word was a joke.
