Guess what turned up on the IFC  channel the other night. Lars Von Trier’s notorious “Antichrist,” and it didn’t appear to have been censored. All the sex, full-frontal nudity and S&M — even Charlotte Gainsbourg’s  bloody sexual  mutilation  — was shown in all its glory.  As I said when I glowingly reviewed “Antichrist” last October  and later named it the best film of 2009, it took guts to make the movie and it takes guts to love it.
