Melbourne?!
As an Aussie, I have to say the opening sequence, supposedly in Melbourne, was pretty groanworthy. The buildings, the accents, the dialogue of the locals -- there was nothing Australian about any of them.
It doesn't matter, and it didn't spoil the movie; I'm just chuckling at the naivety. (Yeah, I know -- "Bali" didn't look or sound like the real Bali, either.)
You might very well think that. I couldn't possibly comment.
