Spy put the question to TVNZ and NZ On Air: does Filthy Rich deserve a second season?
Wrightson is overseas this month but a spokesman for NZ On Air swatted away the nay-sayers: "Outrageous Fortune did not shine in its first season but went forward to huge success."
Andrew Shaw, TVNZ's general manager of commissioning, production and acquisitions, has come back with fighting talk.
"We are very proud of Filthy Rich. It is brave, wild and exciting," he says. "Drama is a great adventure and we are delighted the viewers have enjoyed the ride."
Shaw says audiences won't be disappointed as the season finale approaches.
"They'll be treated to even more twists and turns and surprising revelations as the drama reaches its climax. It really is a drama that keeps audiences guessing to the end."
On average, the show is reaching 250,000 viewers an episode, down from the 406,000 who tuned in for the premiere. However, Shaw says Filthy Rich is winning its time slot with TV2's target audience of 18-49-year-olds.
"Filthy Rich has also been a break-out hit on TVNZ OnDemand with half a million streams since its launch. It's the kind of show that really brings home how we watch TV these days and highlights the big changes we've seen in the way drama is consumed."
With four episodes left, Shaw pushed the season cliffhanger. "We'll finally learn who killed John Truebridge snr and a dangerous confrontation leaves one life hanging in the balance."
Filthy Productions' second drama, Dirty Laundry, appears on TV One later this year.
The show received $6.72m in funding for 13 hours of television - $516,00 an episode.
However, upcoming South Pacific Pictures Outrageous Fortune prequel, TV3's Westside 2, beats that with NZ On Air granting $7.6m for 10 episodes at $760,000 each, making it New Zealand's most expensive drama series.
