So:

I like, I really like, the fact that they can just casually have Patty Hearst guest-star as a not-kidnapped rich person. But it seems to me a sign of why the show is unlikely to have serious ratings success that they decided to keep this fact more or less a secret until one saw the show. That makes it more enjoyable for those who watch it, but decreases the number of people who will. Which is fine with me, until it gets cancelled.
