Caught up! Someone said above it's a soap, but it's way more than that, it's allegorical. The thesis was articulated by Monica in in the season 3 premier:
"The world you live in is slowly shrinking. There's a tiny group of men who are buying it and stripping it naked and selling you what they extract. They're raping your world and selling you what they take."
The acting is soapishly overdone at times, and the script mostly isn't how normal people talk, but the message is spot on and delivered from the perspective of the Duttons, the Indians and environmental activitists.
