Basically, what’s happened to NZ tv drama?

This week The Almighty Johnsons returned and produced a dismal +5 rating of 3 . In its target audience of males 18-49 it rated just a 4, about half of the previous series.

Go Girls has ratings of 5 in +5. Blue Rose on TV2 was a fizzer, rating 3s and 4s in 5+. TV3s Harry did a dismal 3.

It’s a good question. NZ drama has rated well in the past, but at the moment it is all rating pretty badly.
