"The audience size that Barbara was able to capture and harness is unmatched in today's world," said Jackie Jesko, director of the new documentary "Barbara Walters: Tell Me Everything," debuting Monday on Hulu after its premiere at the Tribeca Film Festival earlier this month. "Everything she did sort of made a difference."

There’s nothing wrong with “‘Barbara Walters: Tell Me Everything,” the new Hulu documentary about the late broadcasting icon. It’s an extremely thorough and enjoyable recap of the life of an extraordinary, pioneering television journalist. But it never really goes deeper than that.
