Could have been great if it wasn't for the ending
As I was watching this movie I rather enjoyed it. Even though the lack of a budget was apparently, it still came out well. I did find the characters extremely likable for such a movie, and was rather disappointed to see them be killed off one by one. I wanted to see them get the cure and save the world, or at least live, but instead we got a crop out shell of an ending.
I think it could have been New Zealand's answer to Shaun of the Dead
EDIT: I do like like and enjoy movies with non-Hollywood endings, but this movie didn't build up to it at all. The whole atmosphere was humorous and almost bright. Not something dark where you just expect horrible things to happen, like a Saw movie.
