I have read some of Flixsters' reviews of Australia. I think they are harsh. OK, so this is not Gone with the Wind. But it is similar. Epic movie, wide Australian scenery shots, 2000 cattle stampede, Darwin being hit by Japanese forces in World War II, typical story of good vs evil - a film that leaves many in the theatre crying.
On the flip side, this film has its hokiness - a kid stops the stampede by waving his hand at it, one of the main characters is killed, but no - it is a case of mistaken identity.
All in all, you should watch it - if just to see what all the hullabaloo is about.
