It s entirely fair if you find yourself questioning the filmmaking instincts of Lena Dunham at this point especially after her unwatchable previous film, "Sharp Stick," which posited as its protagonist a young autistic woman, seeking sexual fulfillment in the most idiotic ways imaginable but we can still give her this much. As a storyteller, she has always been very much on top of the physical discomforts of women: Their desires, fears and disappointments, especially when coming to terms with their fledgling womanhood. If you want to make a film about a 14-year-old girl who wants nothing to do with her menstruation cycle Dunham s your huckleberry.
