Is a movie a success if you’re still thinking about it days after viewing? This was the case with Harmony Korine’s Trash Humpers and Lars Von Trier’s Antichrist, two entries in the New York Film Festival that I very nearly walked out on, whose endings could not arrive soon enough, that made me question the credibility, if not sanity, of the selection committee. But the imagery in both was indelible. These are flawed, irritating provocations. And both are worthwhile.
