Coby, the riveting new documentary from director Christian Sonderegger, opens in a small town smack bang in the middle of American Midwest. 23-year-old Suzanna changes gender and becomes a boy: Coby. His transformation deeply disrupts the lives of all who love him – his family, friends and colleagues. Ultimately, Coby’s decision morphs into the transformation of a whole family, compelled to modify their own perspectives. Not only a physical metamorphosis is at stake here, but also a spiritual one that eventually takes place under the director’s bright, unusual eye. Changing has consequences, but so does not doing so.
