Jenner came out publicly as transgender in an interview with Diane Sawyer earlier this year. Last month, the Olympian announced her decision to identify as female in a landmark Vanity Fair cover. This series follows that journey, and even though the trailer is only thirty seconds, it covers a lot of ground, from the private-but-not-private family encounters to a meeting with transgender youth to an emotional moment with Jenner’s mother. It’s an uplifting clip. And why wouldn’t it be? Jenner said in her Vanity Fair piece that she now feels free, and the show looks like it will reflect that freedom. Good for her.
