The first series was quite true to the Nancy Cato book, but here the writers have gone their own sweet way, concentrating on a fairly youthful Delie and Brenton. The trouble is too much of the story is away from the river, and concentrates to a large extent on Brenton. It's very episodic - we don't see the children noticeably age. Although we loosely cover the children's stay at Mrs Melville, we lose the detail about Meg staying on because she's infatuated with their older son - well, Meg here is only a little girl rather than the teenager she ought to have become.
All in all it's a good yarn, although the ending seems hurried and (without giving away the plot) unreasonable. I'd recommend reading the book in which Delie is a real three dimensional character, rather than a fairly cardboard figure. If you can find it, it's still worth giving this sequel a viewing - the acting and camera-work is brilliant, and the producers have done a fine job in creating turn-of-the-century Echuca.
