Kitty Green's "The Assistant" is audacious in a deadpan way, a #MeToo drama that comes on like an HR video illustrating the responsibilities of an entry-level job. The heroine, Jane (Julia Garner), is a junior assistant to the chairman of the company. His name is not Harvey Weinstein. In fact he's never named, or seen. This is a story of sexual abuse in which the predatory behavior, like the abuser, remains behind closed doors, but increasingly obvious to the decreasingly innocent assistant.
