When I'm asked if there are any great New Zealand movies I don't know where to start. Not because there are so many I don't know which ones to choose first, but because the short answer is "No, not really" There are certainly not many I would call "great".
If I pick my favourites from the past 50 years, I can only find about three that I really liked.
