Lars von Trier's latest provocation is an episodic sexual epic called Nymphomaniac, which comes in two two-hour parts, or "volumes," though it's basically one movie sliced in half. The thinking must have been, "Who wants four hours of hardcore sex and philosophizing?," and if you say, "Me, me!," I suggest seeing both back to back: It's an art-house orgy!
Should you see it at all? I recommend it guardedly. It's dumb, but in a bold, ambitious way movies mostly aren't these days, especially when there's sex in the equation. And it's funny, sometimes intentionally.
