It is, on the face of it, a movie about sex, and I can imagine that in our sex-negative culture, there will be those who will take issue with the content of this film. That's sad. It is, simply, a sweet, interesting, deep, honest essay about the nature of being human, and what intimate connection means to us. The story of Mark O'Brien, who lives his life flat on his back, and mostly inside of the iron lung that keeps him breathing, takes an unflinching look at the part that sex plays in the life of a normal adult human. The movie is surprisingly lacking in prurient or sensational cheap shots. Even as the characters engage in frank sexual talk, and work their way along a path toward sexual satisfaction, and even with some significant full frontal nudity, the movie stays steadfastly focused on the human beings at the core of the story -- their hopes and fears and failings and triumphs. John Hawkes, Helen Hunt, and William H. Macy shine. It is well worth a look.
