Nymphomaniac: Vol. I: while the episodic structure follows the usual Lars von Trier’s blueprint, it’s in this case enriched by the meandering conversation between the two main characters that serves as the guideline for the film. By the other hand, the use of sexually explicit images (which may bother viewers, but not this one) caters more to the polemicist than to the storyteller side of von Trier; they are partially justified by the nature of the character. The acting is uneven; Charlotte Gainsbourg and Stellan Skarsgård are both solid, but Stacy Martin is, for the most part, unexpressive.
(Despite being distributed as two separate volumes, this will eventually need to be considered as part of the whole, and not as a stand-alone piece.)
