The Good Doctor is the latest of several serials about a doctor who has been playing with his penis for years and thus starts off by denying that he is indeed a bad guy (and a good one at that) at all. He quickly comes to believe, however, that his secretions of love juice are making a man out of him, which prompts him to spend most of the book telling everyone his story.
For those not familiar with the series, a blue-collar girl named Belle, played by Camilla Belle, becomes obsessed with a cuckolded man who keeps making out with her. She is so determined to prove to him that she isn't as badly off as he makes her out to be that she takes the man's last name and introduces herself as "Belle Van Esterstein." Oh, and if that isn't all sorts of creepy, she also has an extra finger.
Though Dr. Smith is a man of considerable wiles, it seems to me that he has no problem with deceit. Though I'm no Freudian, I would say that the deeper the self-deception and less conscious are the unconscious part of the psyche, the more satisfying it is for the character. His patient is like a newly found toddler, and Dr. Smith seems to delight in playing around with his mind. In fact, a very important concept in Freudian psychology is that the person you are allowing the most to come out.
Belle is perfect as an idealized girl, who never lets on that she is struggling with serious issues of gender identity. She is certainly troubled, but the reader doesn't come to think that she is anything other than trying to get on with the business of living.
Of course, the question is: what is her attraction to the blue-collar girl? I think it is more to do with the tale of how the two women came to meet. Belle somehow became aware of the plight of the elderly couple, who had children, but no husband, and this turned out to be very significant for her, since it fueled her ambition.
Her connection to the couple is unclear, but it may be that she feels a kinship or an interest. She also wishes to redeem herself from past mistakes, and therefore hopes to find a man who will love her in return. Dr. Smith, though, is less interested in saving Belle, whom he sees as being highly flawed, than he is in salvaging his own reputations, if only because he is aware that it would hurt his reputation.
Coming to Daddy, like its sister series, doesn't break new ground. It is a basic story of a man, who must pretend that he is a bad guy and then face up to the idea that he is in fact a good guy. If that is all you are looking for, you'll be okay.
If you are looking for something more, I suggest checking out Pearl Beach, which explores the psychology of the fictitious duo of Tony and Anne, after their discovery that they share some unique qualities. That's not to say that the show itself isn't very good, but I'm just saying that if you have a tendency toward the deeper side of psychological exploration, it would be a very good choice.
