It was a really awesome movie. The accent is adorable. I'll have to visit NZ sometime. No, it's a great movie, really. Different. Makes me want to visit NZ. The nature is incredible. It's a good story. *buying my ticket to NZ*
I don't think it's an ad for NZ anymore than a movie that takes place in the States is an ad for the States. It's a Kiwi movie: Kiwi director, Kiwi actors, Kiwi location. But, yeah. You should visit. The movie didn't include the most gorgeous scenery in NZ, which happens to be in the South Island.
