I love the book - and I love this adaptation. This is TV at its very best. It's beautifully shot and the ensemble cast are superb. Alex Dimitriades as Harry is perhaps the best of all - he captures brilliantly Harry's twitchy machismo and pent-up aggression. Sophie Lowe as Connie is also excellent, simultaneously precocious and vulnerable.
On the whole, it's very faithful to the novel, though the TV writers do make some changes, most of which work well. Some work less well - for instance, unlike in the novel, Anouk knows that something's going on between Hector and Connie. Yet they don't do anything dramatically with her knowledge, so why make the change?
My only other quibble is that Sophie Okonedo, though a very fine actress, is miscast. In the novel, Aisha is Anglo-Indian (as her name suggests), which is an important part of her identity. In the adaptation, her ethnic identity is indeterminate - which isn't bad in itself, but it jars in a series (and novel) in which racial/ethnic identity (Greek, Jewish, Serbian, Anglo-Australian) is shown to be a key faultline in people's interpersonal relationships.
But these are minor flaws in what is a brilliant series. For anybody who wants an insight into middle-class metropolian life in Australia, look no further. It might not be exhaustive - how could it be? - but you'll end up feeling you know Melbourne and some of its people, lovely or not.
