The title of the film “A Fantastic Woman” only means what you first think it does once you get to know its heroine, a transgender singer named Marina Vidal, who is dismissed, denigrated and worse for living what others believe is a “fantasy” existence in Santiago, Chile. Directed by Sebastián Lelio and nominated for an Oscar this year for best foreign language film, “A Fantastic Woman” is masterfully deceptive and even enigmatic.
