opps! That vote was meant to be a reply! Anyway, it's the end of the world scenario, and class wars...of sorts. I've not seen it yet...(I try not to read reviews until after as so many people just tell the story and ruin it)
Yes, based on the review by Jason di Rosso and Judith Lucy, filling in for David ad Margaret on ABC TV's "At the movies", I plan to see it. Probably at the Cremorne Orpheum where it's showing now (and over the coming weeks, I guess).
Here's a link to Jason and Judith's review: http://www.abc.net.au/atthemovies/txt/s4049145.htm
