It's a very rare thing - a New Zealand drama, other than Shortland Street, surviving more than a few series. Westside, the prequel to the hugely popular Outrageous Fortune, is about to launch into its third season - the 10th featuring Auckland's West family. Lynn Freeman talks to writer and co-creator James Griffin about the series' wild Westies, and asks him if writing prequels are easier or harder than sequels. Series Three of Westside starts this week on TV3.
