What a contrast there is among the reviews so far posted about "Operation Buffalo"! Were all these people watching the same show? I have a suspicion that the 1/10 reviews were written by ASIO agents, keen to avoid the scrutiny of the public (as usual).
It is a light satire, set in a cringe-worthy period of Australian history in which politicians routinely doffed their caps to Englishmen (who would have happily let them be over-run by Japanese in 1944).
There are very serious issues to consider in this series: nuclear war, treatment of aboriginal people in the vicinity of the nuclear tests, lack of protection for the soldiers who "volunteered", political intrigue, blackmail, cover-ups, all of which were true to at least some degree. The Wilcox MP character is clearly Richard Casey who spent much of his career trying to knife Menzies PM. Lachlan MP is based on Philip McBride. Both of these worthless pollies were knighted by Menzies and pushed sideways, leaving Menzies to rule as a dictator.
There were times when I laughed uncontrollably in Episode 4 but the humour is generally subtle. There is a dark side to the plot but the writing takes the viewpoint of the soldiers involved and they probably didn't appreciate the danger they were in. Before "This Day Tonight" and the standard of investigative journalism that we have today, ordinary people were unaware of the egregious lack of talent of their leaders. There were Reds under every bed and King Ming was keeping us safe. We were part of an empire on which the sun never set, well didn't set for very long.
If you didn't live through this period, you could not appreciate this series fully.
