Maybe if you are uptight and too serious you will not like this black comedy, but the four of us loved it! "We" were from 23 yrs to 53 yrs, including Japanese, New Zealand, and American nationalities. I often steer clear of black humour because it can be too weird and cruel, but the Aussies did their normal brilliant work on this film and I do recommend it.
There are so many small and big things in this movie that are hugely LAUGH-OUT-LOUD, that we thoroughly enjoyed it.
So, grab a drink, put up your feet, forget about being being conventional, expect the unusual... and prepare for a FUN time (with some serious messages under all of it as well!).
